Product details
Overview
MAX9052BESA+T from Analog Devices is a dual micropower comparator with integrated 2.500V precision voltage reference in an 8-pin SO package. It operates from 2.7V to 5.5V, draws only 55µA supply current, features rail-to-rail inputs/outputs, ±3mV internal hysteresis, and 400ns propagation delay - ideal for battery-powered precision threshold detection in portable instrumentation.
For engineers reviewing the MAX9052BESA+T datasheet, MAX9052BESA+T pinout, MAX9052BESA+T application, or MAX9052BESA+T equivalent, this page delivers verified circuit role (dual comparator + reference), B-grade accuracy (±1% VREF), temperature coefficient (100ppm/°C), rail-to-rail output drive (8mA sink/source), and SO-8 package mapping - all confirmed from Analog Devices' official datasheet Rev 13 (10/23).
Technical Context
The MAX9052BESA+T integrates two independent comparators sharing one precision 2.500V reference, with IN- of Comparator A internally tied to REF and IN- of Comparator B uncommitted - enabling flexible window or level-detection configurations. Its input common-mode range extends from VEE to VCC, with typical input bias current of 1pA and offset voltage of ±1mV over temperature.
The reference uses laser-trimmed thin-film resistors and curvature correction, delivering stable 2.500V output with 100ppm/°C tempco (B grade) and load regulation of 2–6 µV/µA across ±500µA. Output is stable with capacitive loads up to 4.7nF and supports sourcing/sinking up to 500µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - enables direct operation from Li-ion or regulated 3.3V/5V rails without level shifting. |
| Supply Current | 55µA typical at 2.7V - ensures >1-year battery life in coin-cell–powered monitoring systems. |
| Reference Voltage | 2.500V ±1% (B grade) - provides accurate, factory-trimmed threshold for ADC reference or comparator trip points. |
| Propagation Delay | 400ns at 100mV overdrive - supports reliable high-speed signal edge detection in data recovery circuits. |
| Input Offset Voltage | ±1mV max (B grade, -40°C to +85°C) - minimizes false triggering in low-amplitude sensor interfaces. |
| Output Drive | Rail-to-rail push-pull, 8mA sink/source - directly drives LEDs, logic inputs, or small MOSFET gates without external buffers. |
| Reference Tempco | 100ppm/°C (B grade) - limits drift to ±0.85mV over -40°C to +85°C ambient, critical for precision battery voltage monitoring. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator + reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9052AESA | Same SO-8 package and pinout; A-grade reference (±0.4% initial accuracy, 6ppm/°C tempco) vs. B-grade. | Required where tighter reference stability is critical - e.g., precision data acquisition or calibration equipment. | Select MAX9052AESA when long-term accuracy and low thermal drift outweigh cost sensitivity. |
| TLV3702IDR | TI dual comparator (no integrated reference); requires external 2.5V reference; higher supply current (80µA) and slower propagation (1.5µs). | Suitable when reference flexibility is needed (e.g., adjustable thresholds) or when existing reference ICs are already deployed. | Choose TLV3702IDR only if reference voltage must be programmable or shared across multiple devices. |
