Product details
Overview
MAX9053AEUB from Analog Devices is a dual micropower comparator with integrated 2.500V precision voltage reference, operating from 2.7V to 5.5V supply, consuming only 55µA typical supply current, featuring rail-to-rail inputs/outputs, ±3mV internal hysteresis, and 400ns propagation delay - ideal for battery-powered window comparators and precision level translation.
For engineers reviewing the MAX9053AEUB datasheet, MAX9053AEUB pinout, MAX9053AEUB application, or MAX9053AEUB equivalent, this page delivers verified circuit role (dual comparator + reference), package mapping (10-pin µMAX), pin-level design meaning, A-grade accuracy (±0.4% VREF), temperature coefficient (6ppm/°C), and real-world use value in low-power analog monitoring systems.
Technical Context
The MAX9053AEUB integrates two independent comparators sharing one laser-trimmed series-mode voltage reference outputting 2.500V with curvature correction. Its input stage supports common-mode range from VEE −0.25V to VCC +0.25V and exhibits 1.0pA typical input bias current and ±0.5mV typical input offset voltage.
The output stage uses push-pull rail-to-rail drivers capable of sourcing/sinking 8mA, with internal hysteresis eliminating oscillation on slow signals. The reference maintains stability up to 4.7nF capacitive load and achieves 84dB ripple rejection at 120Hz, enabling direct use in noisy supply environments without external filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V - supports single-supply operation across Li-ion, 3.3V, and 5V systems without level shifting. |
| Supply Current (Typ) | 55µA at VCC = 2.7V - enables >1-year battery life in coin-cell–powered sensor nodes switching at <1Hz. |
| Reference Voltage | 2.500V ±0.4% (A grade) - provides stable threshold for ADC reference, DAC biasing, or overvoltage detection. |
| Propagation Delay | 400ns at 100mV overdrive - ensures timely response in fast edge-detection circuits like pulse-width monitors. |
| Input Offset Voltage | ±0.5mV (typ) - enables accurate differential sensing down to sub-millivolt signal levels. |
| Common-Mode Range | VEE −0.25V to VCC +0.25V - allows direct interface to sensors operating beyond supply rails (e.g., thermocouples). |
| Output Drive | Rail-to-rail push-pull, ±8mA - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
Pinout & Package
The MAX9053AEUB is housed in a 10-pin µMAX package (outline 21-0061), RoHS-compliant, with exposed pad for thermal enhancement and compact 3mm × 3mm footprint suitable for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply input - must be bypassed with 100nF capacitor near pin for noise immunity. |
| 2 | N.C. | No connection - not internally bonded; leave unconnected and unpopulated on PCB. |
| 3 | OUTB | Comparator B output - push-pull, rail-to-rail, sinks/sources up to 8mA. |
| 4 | INB− | Comparator B inverting input - high-impedance node; sensitive to stray capacitance and EMI. |
| 5 | INA+ | Comparator A noninverting input - accepts signals up to VCC +0.25V for over-rail sensing. |
| 6 | INA− | Comparator A inverting input - uncommitted; may be tied to REF or external feedback network. |
| 7 | REF | Precision 2.500V reference output - stable with 0–4.7nF load; supplies bias for both comparators. |
| 8 | VEE | Negative supply (typically GND) - return path for reference and comparator quiescent current. |
| 9 | OUTA | Comparator A output - identical electrical behavior to OUTB; supports independent logic-level generation. |
| 10 | INB+ | Comparator B noninverting input - matches INA+ in voltage range and bias characteristics. |
Key Features
| Feature | Design Value |
|---|---|
| Dual comparator + reference integration | Reduces component count by 3–4 discrete parts (two comparators + reference + decoupling) in window detector designs. |
| A-grade reference accuracy | ±0.4% initial error and 6ppm/°C tempco enable ±0.5% total error over −40°C to +85°C - sufficient for Class I energy metering thresholds. |
| Rail-to-rail input with extended range | Accepts inputs 250mV beyond rails - eliminates need for external level-shifting op-amps when interfacing to ±10V industrial sensors. |
| Low dynamic supply current surge | Minimal ICC spike during output transitions reduces supply-line noise - avoids mandatory large bulk capacitors in ultra-low-noise analog front ends. |
| Stable with capacitive loads up to 4.7nF | Permits direct connection to long traces, connectors, or ADC input capacitors without oscillation risk. |
Applications
| Battery Voltage Window Monitor | Industrial Sensor Threshold Detection |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage between 2.8V (low warning) and 4.2V (overvoltage cutoff) in portable medical devices. IC Role / Device Role / Timing Role: Dual comparator compares cell voltage against 2.500V reference-derived thresholds using resistor dividers; REF supplies stable bias. Use Value: 55µA total quiescent current extends battery life >2 years in standby; ±0.4% reference accuracy ensures reliable trip points across temperature. | Use Scenario: Detecting out-of-range 4–20mA loop current in PLC analog input modules. IC Role / Device Role / Timing Role: One comparator monitors loop voltage drop across shunt; second validates auxiliary supply rail - both referenced to same 2.500V REF. Use Value: Common reference eliminates ratio errors; rail-to-rail inputs accept shunt voltages up to 5V without attenuation. |
| Optical Receiver Signal Discrimination | Microcontroller Wake-Up Comparator |
Use Scenario: Converting weak, noisy IR receiver diode output into clean digital pulses for remote control decoding. IC Role / Device Role / Timing Role: Comparator A detects rising edge of modulated carrier; Comparator B provides hysteresis-enhanced noise immunity on falling edge. Use Value: 400ns propagation delay preserves 2.4kHz carrier fidelity; internal ±3mV hysteresis rejects RF interference without external components. | Use Scenario: Waking an ARM Cortex-M0 microcontroller from deep sleep when external sensor exceeds threshold. IC Role / Device Role / Timing Role: Comparator A triggers wake-up interrupt; Comparator B monitors system VDD for brown-out protection - both share REF for consistent scaling. Use Value: 55µA supply current minimizes sleep-mode power penalty; REF turn-on settling time <200µs ensures rapid system readiness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator + precision reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9053BEUB | B-grade reference (±1% initial accuracy, 100ppm/°C tempco); otherwise identical pinout, supply current, and speed. | Suitable where cost sensitivity outweighs precision - e.g., consumer appliance status indicators. | Select MAX9053BEUB only if ±1% reference tolerance meets system error budget; avoid in metrology-critical paths. |
| TLV3702IDR | Single-supply dual comparator only (no integrated reference); requires external 2.5V reference; higher supply current (80µA typ). | Used when reference voltage must be programmable or shared across multiple ICs - e.g., multi-channel data acquisition. | Choose TLV3702IDR when flexibility in reference selection or lower unit cost justifies added BOM complexity and higher power. |
Compared with MAX9053BEUB and TLV3702IDR, the MAX9053AEUB uniquely delivers guaranteed ±0.4% reference accuracy, lowest quiescent current among integrated dual-comparator solutions, and seamless compatibility with µMAX footprints - making it optimal for precision, space-, and power-constrained designs.

FAQ
What is the reference voltage accuracy and temperature coefficient of the MAX9053AEUB?
The MAX9053AEUB features an A-grade precision voltage reference with ±0.4% initial accuracy at +25°C and a typical temperature coefficient of 6ppm/°C over −40°C to +85°C. This specification is laser-trimmed and verified per production test, ensuring stable 2.500V output for critical threshold generation in the MAX9053AEUB.
Does the MAX9053AEUB require an external output capacitor on the REF pin?
No, the MAX9053AEUB does not require an external capacitor on the REF pin for stability - it is inherently stable with capacitive loads from 0 to 4.7nF. An external capacitor may be added only to improve transient response during step-load changes, but it is optional and not needed for basic operation of the MAX9053AEUB.
What is the maximum capacitive load the MAX9053AEUB comparators can drive directly?
The MAX9053AEUB comparators feature rail-to-rail push-pull outputs rated for ±8mA drive strength. While no explicit maximum capacitive load is specified for the comparator outputs, typical rise/fall times remain under 80ns with 200pF load (CL = 200pF), confirming robust driving capability for standard logic inputs and moderate PCB trace capacitance in the MAX9053AEUB.
Can the MAX9053AEUB operate from a 2.5V supply?
No - the MAX9053AEUB has a minimum supply voltage of 2.7V, as specified in its Absolute Maximum Ratings and Electrical Characteristics tables. Operating below 2.7V risks undefined comparator behavior and reference instability. For 2.5V-compatible alternatives, consider the MAX9042/MAX9043 series, which support 2.5V to 5.5V operation - but note these differ in reference voltage (2.048V) and are not drop-in replacements for the MAX9053AEUB.
How is the internal hysteresis implemented in the MAX9053AEUB, and can it be adjusted?
The MAX9053AEUB includes fixed internal hysteresis of ±3mV, implemented via on-chip positive feedback. This hysteresis is not user-adjustable but ensures clean switching with slow-moving inputs. External hysteresis can be added using two resistors in a feedback network from OUT to IN+, as detailed in the MAX9053AEUB datasheet Figure 1 - allowing custom trip-point separation while retaining the core functionality of the MAX9053AEUB.
