Product details
Overview
MAX9052AESA-T from Analog Devices is a dual comparator with integrated 2.500V precision voltage reference in an 8-pin SO package, operating from 2.7V to 5.5V supply. It delivers rail-to-rail inputs/outputs, 400ns propagation delay, ±3mV internal hysteresis, and 55µA supply current-ideal for low-power battery management and window detection circuits.
For engineers reviewing the MAX9052AESA-T datasheet, MAX9052AESA-T pinout, MAX9052AESA-T application, or MAX9052AESA-T equivalent, this page provides verified functional context, validated pin roles, confirmed A-grade reference accuracy (±0.4% initial, 6ppm/°C), and real-world design implications for precision analog thresholding.
Technical Context
The MAX9052AESA-T integrates two independent comparators sharing one laser-trimmed series-mode voltage reference. Its input stage supports common-mode voltage from VEE – 0.25V to VCC + 0.25V, with typical 1.0pA input bias current and ±0.5mV offset voltage. Internal hysteresis ensures noise-immune switching without external components.
The output stage uses a push-pull rail-to-rail driver capable of sinking and sourcing up to 8mA, while limiting supply-current surges during transitions-reducing power-supply glitches. The 2.500V reference features curvature correction, stable operation with up to 4.7nF capacitive load, and 84dB ripple rejection at 120Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - enables direct use in Li-ion and 3.3V/5V systems without level shifting |
| Supply Current | 55µA typical at 2.7V - extends battery life in always-on monitoring applications |
| Reference Voltage | 2.500V ±0.4% (A grade) - provides accurate, stable threshold for ADC reference or comparator trip points |
| Propagation Delay | 400ns at 100mV overdrive - supports fast response in timing-critical window detection |
| Input Offset Voltage | ±0.5mV typical - minimizes false triggering in low-differential-signal applications like IR receivers |
| Common-Mode Range | VEE – 0.25V to VCC + 0.25V - allows sensing beyond rails, e.g., detecting overvoltage on 5V bus with 3.3V supply |
| Output Drive | Rail-to-rail, ±8mA - directly interfaces with logic families or drives small loads without external buffers |
Pinout & Package
MAX9052AESA-T is housed in an 8-pin SO (Small Outline) package with standard 150mil width and gull-wing leads. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Comparator A Output | Push-pull rail-to-rail output; sinks/sources up to 8mA; no external pull-up required |
| 2 (INA+) | Comparator A Noninverting Input | High-impedance node (1pA bias); accepts signals up to VCC + 0.25V |
| 3 (INB–) | Comparator B Inverting Input | Uncommitted input; usable as standalone threshold or feedback node |
| 4 (VEE) | Negative Supply | Ground reference for single-supply operation; must be connected to system GND |
| 5 (VCC) | Positive Supply | Accepts 2.7V–5.5V; bypass capacitor recommended if supply impedance >1Ω |
| 6 (REF) | Precision Reference Output | 2.500V ±0.4%, stable with ≤4.7nF load; supplies both comparators' reference needs |
| 7 (INB+) | Comparator B Noninverting Input | Independent high-Z input; enables dual-threshold or window-comparator configurations |
| 8 (OUTB) | Comparator B Output | Independent push-pull output; synchronized switching not guaranteed between OUTA/OUTB |
Key Features
| Feature | Design Value |
|---|---|
| Dual comparator + precision reference | Reduces board space and BOM count vs. discrete comparator + external reference solution |

| Rail-to-rail I/O with extended CMVR | Supports direct sensing of signals beyond supply rails-e.g., detecting 5.2V overvoltage on 5V line |
| Low dynamic supply current surge | Eliminates need for large local bypass caps; reduces PCB area and EMI from supply transients |
| Internal ±3mV hysteresis | Prevents chatter on slow-moving inputs (e.g., thermistor outputs), eliminating external hysteresis resistors |
Applications
| Precision Battery Management | Window Comparators |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles to enforce 2.5V–4.2V safe operating window. IC Role / Device Role / Timing Role: Dual comparator compares cell voltage against 2.500V REF (low threshold) and externally derived high threshold; REF provides stable reference for both. Use Value: Eliminates separate voltage dividers and reference ICs-reducing component count and thermal drift errors in portable medical devices. | Use Scenario: Detecting valid signal amplitude in industrial sensor interfaces where output must stay within defined upper/lower bounds. IC Role / Device Role / Timing Role: One comparator monitors upper limit (INB+ tied to scaled REF), the other lower limit (INA+ tied to REF); outputs feed AND gate. Use Value: 400ns delay and rail-to-rail drive ensure fast, jitter-free window violation detection in PLC analog input modules. |
| IR Receivers | Level Translators |
Use Scenario: Converting weak, noisy IR photodiode signals into clean digital pulses for microcontroller decoding. IC Role / Device Role / Timing Role: Comparator A amplifies and thresholds modulated IR carrier; internal hysteresis rejects ambient light noise. Use Value: 1pA input bias and ±0.5mV offset preserve signal integrity from high-impedance photodiodes-critical for remote control range. | Use Scenario: Translating 5V logic signals to 3.3V microcontroller inputs in mixed-voltage embedded systems. IC Role / Device Role / Timing Role: Comparator A compares 5V signal to 2.500V REF; output swings rail-to-rail between 0V and 3.3V. Use Value: Push-pull output eliminates external pull-up resistor-reducing power consumption and layout complexity in IoT edge nodes. |
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 |
|---|---|---|---|
| MAX9052BEUA | Same dual-comparator + 2.500V reference core, but in 8-pin µMAX package (3mm × 3mm) | Higher density layout; requires different land pattern and reflow profile (JEDEC 020A Class 3) | Select when board space is constrained and µMAX assembly capability exists |
| TLV3702IDR | Dual comparator only (no integrated reference); requires external 2.5V reference (e.g., REF3025) | Greater flexibility in reference selection but adds BOM cost, layout area, and potential drift mismatch | Select when reference voltage must be adjustable or higher accuracy (>0.1%) is needed |
Compared with MAX9052BEUA, the MAX9052AESA-T offers identical electrical performance in a larger, wave-solderable SO package-simplifying prototyping and high-reliability industrial assembly. Versus TLV3702IDR + REF3025, it trades design flexibility for reduced component count, lower total drift, and faster time-to-market in fixed-threshold applications.

FAQ
What is the reference voltage accuracy and temperature coefficient of the MAX9052AESA-T?
The MAX9052AESA-T features an A-grade 2.500V precision reference with ±0.4% initial accuracy over temperature and a typical temperature coefficient of 6ppm/°C. This specification is guaranteed across the –40°C to +85°C operating range and enables sub-10mV total drift in precision thresholding applications without calibration.
Does the MAX9052AESA-T require an external capacitor on the REF pin?
No, the MAX9052AESA-T does not require an external capacitor on the REF pin for stability-it is internally compensated and remains stable with capacitive loads up to 4.7nF. An optional 100nF ceramic capacitor may be added to improve transient response if the reference supplies rapidly varying loads, but it is not mandatory for basic operation.
Can both comparators in the MAX9052AESA-T share the same reference voltage?
Yes, the MAX9052AESA-T's single 2.500V reference (pin 6) is internally routed to both comparators, enabling consistent, matched thresholding without external routing. This eliminates inter-channel reference mismatch and simplifies design of dual-threshold or window-comparator circuits using the MAX9052AESA-T.
What is the maximum capacitive load the MAX9052AESA-T output can drive?
The MAX9052AESA-T output stages are rated to drive ≥15pF loads with full 400ns propagation delay specification. While not explicitly limited, typical applications use ≤50pF (including PCB trace capacitance). For heavier loads (e.g., >100pF), propagation delay increases-verified in the datasheet's "Propagation Delay vs. Capacitive Load" curves for both 2.7V and 5V supply conditions.
Is the MAX9052AESA-T pin-compatible with other devices in the MAX905x family?
Yes, the MAX9052AESA-T shares the same 8-pin SO pinout with MAX9052BESA, MAX9052AEUA, and MAX9052BEUA. However, it is not pin-compatible with MAX9050/MAX9051 (5-/6-pin SOT23) or MAX9053 (10-pin µMAX). Always verify top-mark codes and grade markings (A vs. B) when substituting, as reference accuracy and tempco differ.
