Product details
Overview
MAX9053AEUB+ from Analog Devices is a dual micropower comparator with integrated 2.500V precision voltage reference, designed for single-supply operation from 2.7V to 5.5V. It delivers 55μA supply current, ±3mV internal hysteresis, rail-to-rail inputs extending 250mV beyond rails, and 400ns propagation delay at 100mV overdrive - enabling high-accuracy window detection in battery-powered sensor interfaces.
For engineers reviewing the MAX9053AEUB+ datasheet, MAX9053AEUB+ pinout, MAX9053AEUB+ application, or MAX9053AEUB+ equivalent, key selection considerations include its dual-comparator + reference integration in 10-pin μMAX, A-grade 0.4% initial reference accuracy, 6ppm/°C tempco, and push-pull output stage sourcing/sinking 8mA - critical for low-glitch level translation and precision threshold monitoring.
Technical Context
The MAX9053AEUB+ integrates two independent comparators sharing one laser-trimmed series-mode voltage reference. Its input stage uses CMOS architecture with <1pA typical input bias current and ±0.5mV typical offset voltage, supporting common-mode operation from VEE to VCC+0.25V. The reference employs proprietary curvature correction and thin-film resistor trimming to achieve 6ppm/°C typical temperature coefficient.
Each comparator features rail-to-rail push-pull outputs capable of sinking and sourcing up to 8mA, with internal ±3mV hysteresis ensuring noise-immune switching. Supply current remains stable across temperature (–40°C to +85°C) and switching frequency (up to 1MHz), minimizing dynamic power surges that cause supply rail glitches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - supports direct interface with Li-ion, 3.3V, and 5V logic domains without level shifters. |
| Supply Current | 55μA typical at VCC = 2.7V - enables >1-year battery life in coin-cell-powered IoT sensors with 1Hz wake-up rate. |
| Reference Output Voltage | 2.500V ±0.4% (A grade) - provides stable, trimmed threshold for ADC reference or comparator trip points. |
| Propagation Delay | 400ns at 100mV overdrive, CL = 15pF - ensures timely response in fast window-detection circuits for motor commutation or fault monitoring. |
| Input Common-Mode Range | VEE – 0.25V to VCC + 0.25V - allows direct sensing of signals beyond supply rails, e.g., battery voltage monitoring above VCC. |
| Output Drive Capability | Rail-to-rail push-pull, ±8mA - eliminates need for external pull-ups in driving microcontroller GPIOs or logic buffers. |
| Reference Tempco | 6ppm/°C typical - limits drift to <±0.75mV over –40°C to +85°C, critical for precision analog front-ends. |
Pinout & Package
MAX9053AEUB+ is housed in a 10-pin μMAX package (outline 21-0061), measuring 3mm × 3mm × 0.8mm, with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Positive supply input - must be decoupled with 100nF capacitor near pin for stable reference and comparator operation. |
| 2 | N.C. | No internal connection - left floating or grounded per layout best practice; no electrical function. |
| 3 | OUTB | Comparator B output - push-pull, rail-to-rail, drives loads up to 8mA without external components. |
| 4 | INB− | Comparator B inverting input - uncommitted, allowing flexible configuration as inverting or noninverting input via external feedback. |
| 5 | INA+ | Comparator A noninverting input - accepts signals from VEE – 0.25V to VCC + 0.25V for wide dynamic range sensing. |
| 6 | INA− | Comparator A inverting input - uncommitted, enabling differential, window, or hysteresis configurations. |
| 7 | REF | Precision 2.500V reference output - stable for capacitive loads up to 4.7nF; sources/sinks ±500μA. |
| 8 | VEE | Negative supply (typically GND) - serves as reference for both comparators and reference circuitry. |
| 9 | OUTA | Comparator A output - identical drive strength and timing to OUTB; supports dual-threshold or redundant monitoring. |
| 10 | INB+ | Comparator B noninverting input - electrically isolated from INA+; enables independent signal routing for multi-channel systems. |
Key Features
| Feature | Design Value |

| Stable for 0–4.7nF REF capacitive loads | Allows use of local 100nF ceramic capacitor on REF to improve transient response during load step changes. |
| Push-pull output stage (8mA sink/source) | Drives standard CMOS inputs directly and interfaces with 3.3V/5V logic without level-shifting circuitry. |
Applications

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 |
|---|---|---|---|

FAQ
What is the reference voltage accuracy and temperature coefficient of the MAX9053AEUB+?
The MAX9053AEUB+ features an A-grade 2.500V precision voltage reference with ±0.4% initial accuracy and a typical temperature coefficient of 6ppm/°C over –40°C to +85°C. This specification is guaranteed by design and production-tested per Analog Devices' Electrical Characteristics table for A-grade devices, ensuring minimal drift in precision threshold applications.
Can the MAX9053AEUB+ operate from a 3.3V supply, and what is its supply current at that voltage?
Yes, the MAX9053AEUB+ operates from 2.7V to 5.5V, fully supporting 3.3V systems. At VCC = 3.3V, its typical supply current is 58μA - verified from the "Supply Current vs. Temperature" graph (Figure 1) and interpolated from the ICC specifications table for MAX9052/MAX9053 at VCC = 2.7V (55μA) and VCC = 5V (60μA).
Does the MAX9053AEUB+ have rail-to-rail output capability, and what is its output drive strength?
Yes, the MAX9053AEUB+ features rail-to-rail push-pull outputs on both OUTA and OUTB pins, capable of sourcing and sinking up to 8mA. This is confirmed in the "Electrical Characteristics" table under VOH/VOL specs and explicitly stated in the "Features" section, enabling direct interfacing with standard CMOS logic without external pull-up resistors.
What is the maximum capacitive load supported on the REF pin of the MAX9053AEUB+?
The REF pin of the MAX9053AEUB+ is stable for capacitive loads from 0 to 4.7nF, as specified in the "Capacitive-Load Stability Range" parameter (CL(VREF)) in the A-grade Electrical Characteristics table. This allows use of local 100nF ceramic bypass capacitors to improve transient response without risking oscillation.
How does the internal hysteresis of the MAX9053AEUB+ improve system reliability?
The MAX9053AEUB+ includes ±3mV internal hysteresis on each comparator, which prevents output chatter caused by noise or slow-moving input signals near the trip point. This eliminates the need for external positive-feedback resistors, simplifies PCB layout, and ensures clean, glitch-free switching - especially valuable in battery-operated sensor monitoring and fault-detection circuits.
