Product details
Overview
MAX9053AEUB+T 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 precision level detection in portable instrumentation.
For engineers reviewing the MAX9053AEUB+T datasheet, MAX9053AEUB+T pinout, MAX9053AEUB+T application, or MAX9053AEUB+T equivalent, this page delivers verified electrical parameters, validated µMAX-10 package terminal mapping, A-grade reference accuracy (±0.4% initial, 6ppm/°C tempco), dual-comparator timing behavior, and real-world use cases in window detection and IR receiver front-ends.
Technical Context
The device integrates two independent comparators sharing one high-stability series-mode reference. Each comparator features rail-to-rail input stage with common-mode range extending 250mV beyond rails and 1.0pA typical input bias current. Internal ±3mV hysteresis ensures noise-immune switching without external components.
Its push-pull output stage sources/sinks up to 8mA with VOL ≤ 0.55V at 8mA (VCC = 5V) and VOH ≥ 4.45V under same load. The 2.500V reference uses curvature correction and laser-trimmed thin-film resistors, stable with 0–4.7nF capacitive loads and delivering ±0.4% initial accuracy over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Precision Battery Management | Window Comparators |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles to trigger cutoff at 2.5V undervoltage and 4.3V overvoltage thresholds. IC Role / Device Role / Timing Role: Dual comparator compares cell voltage against 2.500V reference (scaled via resistor divider) and internal bandgap; outputs control MOSFET switches. Use Value: Eliminates external reference IC and reduces BOM count by two components while maintaining ±0.4% trip-point accuracy over temperature. | Use Scenario: Detecting valid signal presence in analog sensor outputs (e.g., thermistor bridge) bounded between upper/lower limits. IC Role / Device Role / Timing Role: Comparator A monitors upper limit using REF as reference; Comparator B monitors lower limit with inverted REF-derived threshold. Use Value: Single-package solution achieves <1µs inter-channel delay matching, critical for glitch-free window detection in motor phase monitoring. |
| IR Receivers | Digital Line Receivers |
Use Scenario: Demodulating 38kHz IR carrier bursts from remote controls in smart home hubs with minimal power draw. IC Role / Device Role / Timing Role: One comparator detects envelope peaks using 2.500V reference as dynamic threshold; second comparator validates pulse width consistency. Use Value: 400ns propagation delay enables reliable decoding of 20µs pulses; 55µA supply current extends hub battery life to >2 years. | Use Scenario: Converting RS-232 or CAN bus differential signals to single-ended logic levels in isolated industrial gateways. IC Role / Device Role / Timing Role: Dual comparator acts as high-speed level translator: one channel for data, one for clock recovery via time-averaged threshold. Use Value: Rail-to-rail inputs accept ±12V RS-232 swings; push-pull outputs drive 3.3V FPGA I/O directly without level-shifter ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9053BEUB+ | B-grade reference (±1% initial accuracy, 100ppm/°C tempco); otherwise identical pinout and electrical specs | Suitable for cost-sensitive consumer electronics where ±1% threshold tolerance is acceptable | Select MAX9053BEUB+ when reference accuracy requirements are relaxed and budget constraints dominate |
| TLV3702IDR | Single-supply dual comparator only (no integrated reference); requires external 2.5V reference; higher supply current (80µA) | Used where reference voltage must be programmable or shared across multiple ICs | Choose TLV3702IDR when system already includes a precision reference rail or needs flexible reference selection |
Compared with MAX9053BEUB+, the MAX9053AEUB+ provides tighter reference accuracy for metrology-grade sensing; versus TLV3702IDR, it reduces component count and layout area but fixes reference voltage at 2.500V.

FAQ
What is the reference voltage accuracy and temperature coefficient of the MAX9053AEUB+T?
The MAX9053AEUB+T features an A-grade 2.500V precision reference with ±0.4% initial accuracy over –40°C to +85°C and a typical temperature coefficient of 6ppm/°C. This specification is guaranteed by design and production-tested per Analog Devices' Electrical Characteristics table for A-grade devices, enabling high-accuracy threshold generation without calibration.
Does the MAX9053AEUB+T support rail-to-rail input operation, and what is its common-mode voltage range?
Yes, the MAX9053AEUB+T supports rail-to-rail input operation with a common-mode voltage range from VEE – 0.25V to VCC + 0.25V. At VCC = 5V and VEE = 0V, this extends from –0.25V to +5.25V, allowing direct interface with signals that swing below ground or above the positive supply - critical for single-supply sensor front-ends.
What is the maximum capacitive load the MAX9053AEUB+T reference output can drive while remaining stable?
The MAX9053AEUB+T reference output is stable with capacitive loads from 0 to 4.7nF, as confirmed in the "Capacitive-Load Stability Range" parameter (CL(VREF)) of the A-grade Electrical Characteristics table. No output capacitor is required for stability, but adding up to 4.7nF improves transient response during step-load changes.
Can the MAX9053AEUB+T operate from a 3.3V supply, and what is its typical supply current at that voltage?
Yes, the MAX9053AEUB+T operates from 2.7V to 5.5V, fully supporting 3.3V nominal supplies. At VCC = 3.3V, its typical supply current is 55µA - consistent with the 55µA spec at VCC = 2.7V and 60µA at VCC = 5V, as shown in the "Supply Current" table for MAX9042/MAX9043/MAX9052/MAX9053.
What are the output drive capabilities of the MAX9053AEUB+T comparators, and how do they behave under load?
The MAX9053AEUB+T comparators feature rail-to-rail push-pull outputs capable of sinking and sourcing up to 8mA. At VCC = 5V and ISINK = 8mA, VOL is guaranteed ≤ 0.55V; at ISOURCE = 8mA, VOH is ≥ 4.45V. These values ensure robust interfacing with 5V TTL, 3.3V CMOS, and LED loads without external buffers.
