Product details
Overview
MAX967EUA-TG069 from Maxim Integrated is a dual micropower comparator with rail-to-rail inputs/outputs, 1.235V ±1.5% internal reference, programmable hysteresis (±1mV to ±50mV), and 3µA per comparator supply current at +3V. It operates from +1.6V to +5.5V single supply and is designed for ultra-low-voltage 2-cell battery-powered systems requiring precise threshold detection with noise immunity.
For engineers reviewing the MAX967EUA-TG069 datasheet, MAX967EUA-TG069 pinout, MAX967EUA-TG069 application, or MAX967EUA-TG069 equivalent, this page delivers verified electrical parameters, µMAX-8 package terminal mapping, dual-voltage-monitor configuration details, and real-world design guidance for battery-sensing, window-comparator, and level-translation use cases.
Technical Context
The MAX967EUA-TG069 integrates two independent comparators sharing a common 1.235V bandgap reference and a single HYST pin that programs identical hysteresis for both channels. Its input common-mode range extends from –0.25V to VCC, enabling operation near ground or rail in low-voltage systems.
Each comparator features open-drain output capable of sinking up to 10mA (at VCC = 2V) with VOL ≤ 400mV at 100µA load, and propagation delay of 10µs (50mV overdrive). The internal reference sources up to 50µA with ±2.5% accuracy across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.6V to +5.5V - supports direct connection to 2-cell alkaline/NiMH (2.4–3.2V) or Li-ion (3.0–4.2V) batteries without regulation. |
| Quiescent Current | 3µA per comparator - enables >1-year battery life in always-on voltage-monitor applications with 200mAh coin cell. |
| Reference Voltage | 1.235V ±1.5% (0°C to +85°C) - provides stable trip-point anchor for precision threshold detection without external components. |
| Hysteresis Range | Programmable ±1mV to ±50mV via HYST pin - suppresses chatter in noisy environments such as motor-driven portable equipment. |
| Propagation Delay | 10µs at 50mV overdrive - sufficient for slow-varying signals like battery voltage decay or thermal thresholds. |
| Input Offset Voltage | ±1mV max - ensures accurate switching at small differential voltages, critical for tight-window monitoring. |
| Common-Mode Range | –0.25V to VCC - allows direct sensing of signals below ground (e.g., current-sense shunt on low-side) or above VCC via resistive dividers. |
Pinout & Package
MAX967EUA-TG069 is housed in an 8-pin µMAX package (U8-1), 3.05mm × 3.05mm × 0.8mm body, with exposed pad for thermal enhancement. Pin 1 marked by dot; pin count clockwise from top-left corner when viewed top-down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up to any voltage ≤6V (including higher than VCC) for level translation. |
| 2 | GND | Analog/digital ground reference - must be low-impedance connection shared with REF and HYST for reference stability. |
| 3 | INB+ | Inverting input of Comparator B - used with INB– to configure B as high-threshold detector in dual-monitor setup. |
| 4 | INB– | Noninverting input of Comparator B - paired with INB+ to form window-comparator upper/lower bounds when used with MAX967's shared hysteresis. |
| 5 | INA– | Inverting input of Comparator A - typically connected to resistor divider for VCC monitoring or sensor signal. |
| 6 | INA+ | Noninverting input of Comparator A - tied to REF or external threshold for fixed-level detection. |
| 7 | VCC | Positive supply input - powers both comparators and internal reference; bypass with 100nF ceramic capacitor close to pin. |
| 8 | REF | 1.235V reference output - supplies precision voltage to INA+/INB+ and HYST; decouple with 0.1µF capacitor to reduce noise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates down to –0.25V and up to VCC - enables direct interface with unbuffered sensors or shunt-based current monitors without level-shifting circuitry. |
| Shared programmable hysteresis | Single HYST pin controls hysteresis for both comparators - simplifies PCB layout and component count in dual-threshold designs like power-good + brownout detection. |
| Internal 1.235V ±1.5% reference | Eliminates need for external precision reference IC or resistor divider - reduces BOM cost and improves long-term drift performance in battery-operated devices. |
| Ultra-low 3µA supply current | Enables continuous monitoring during sleep modes - critical for IoT endpoints where wake-up latency must be minimized without sacrificing battery life. |
| Open-drain outputs with 6V tolerance | Supports mixed-voltage systems (e.g., 1.8V comparator driving 3.3V or 5V logic) - removes need for discrete level translators in multi-rail embedded designs. |
Applications
| Battery Voltage Monitor | Window Comparator |
|---|---|
|

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 |
|---|---|---|---|
| MAX965EUA-T | Single comparator, same µMAX-8 package, identical reference/hysteresis specs, 3µA supply current. | Lacks second comparator channel - requires duplication for dual-threshold functions, increasing board space and BOM count. | Select when only one threshold detection is needed and board area is constrained; not suitable for window or dual-monitor use. |
| TLV3702IDR | Dual comparator with rail-to-rail I/O, 1.8V min supply, but no internal reference; 850nA supply current; SOIC-8 package. | Requires external reference or resistor divider for precise thresholds; lower quiescent current but higher design complexity for accuracy-critical apps. | Select for ultra-low-power applications where reference accuracy is secondary and external components are acceptable. |
Compared with MAX967EUA-TG069, MAX965EUA-T halves channel count but matches all key specs per comparator, while TLV3702IDR trades integrated reference for lower IQ and lacks hysteresis programming - making MAX967EUA-TG069 optimal for compact, self-contained dual-threshold monitoring.

FAQ
What is the operating temperature range for MAX967EUA-TG069?
The MAX967EUA-TG069 is specified for operation from –40°C to +85°C. All key parameters-including reference voltage accuracy (±2.5%), input offset voltage (±1mV), and supply current (3µA)-are guaranteed across this extended industrial temperature range, making it suitable for automotive cabin modules and outdoor portable equipment.
Does MAX967EUA-TG069 require external components to use its internal reference?
Yes, the MAX967EUA-TG069 internal 1.235V reference requires a 0.1µF ceramic capacitor between REF and GND for noise reduction and stability. Without this capacitor, reference output noise increases to ~1.0mV p-p, degrading comparator accuracy in precision threshold applications. No resistors or additional ICs are needed for basic reference use.
Can MAX967EUA-TG069 drive a 5V logic input directly?
Yes, MAX967EUA-TG069 can drive 5V logic inputs directly using its open-drain outputs. Connect OUTA or OUTB to a 5V pull-up resistor (e.g., 10kΩ); the output will sink current when active and float to 5V when inactive. The device tolerates output voltages up to 6V, ensuring safe interfacing with 5V CMOS/TTL loads without level-shifting circuitry.
How is hysteresis programmed on MAX967EUA-TG069?
Hysteresis on MAX967EUA-TG069 is programmed by connecting two external resistors between REF, HYST, and GND. With R1 from REF to HYST and R2 from HYST to GND, hysteresis band ≈ 2 × (VREF − VHYST). For ±25mV hysteresis, typical values are R1 = 49.9kΩ and R2 = 2.4MΩ. HYST must remain within VREF − 50mV to VREF to avoid undefined behavior.
Is MAX967EUA-TG069 pin-compatible with other devices in the MAX965–MAX970 family?
MAX967EUA-TG069 shares the same 8-pin µMAX package and pinout as MAX965EUA-T, MAX966EUA-T, and MAX968EUA-T. However, functionality differs: MAX966 lacks REF and HYST pins (N.C.), while MAX968 configures INB−/INB+ as window-comparator inputs. Direct substitution is not recommended without verifying schematic compatibility for REF/HYST usage.
