Product details
Overview
MAX989EUA-TG069 from Maxim Integrated is a dual micropower rail-to-rail input/output comparator with push-pull output stage, operating from 2.5V to 5.5V single supply (or ±1.25V to ±2.75V dual supply), consuming only 11µA per comparator, achieving 300ns propagation delay at 100mV overdrive, and supporting 8mA output drive capability - ideal for battery-powered zero-crossing detection and threshold monitoring in portable instrumentation.
For engineers reviewing the MAX989EUA-TG069 datasheet, MAX989EUA-TG069 pinout, MAX989EUA-TG069 application, or MAX989EUA-TG069 equivalent, key selection criteria include guaranteed 300ns propagation delay across -40°C to +85°C, ±0.5mV typical input offset voltage, rail-to-rail common-mode input range extending 250mV beyond rails, and push-pull output compatibility with 3V/5V logic interfaces without external pull-up resistors.
Technical Context
The MAX989EUA-TG069 integrates two independent comparators sharing a common VCC and VEE supply, each featuring internal 3mV hysteresis to prevent chatter on slow-moving inputs and eliminating need for external hysteresis networks in basic threshold applications. Its input stage accepts common-mode voltages from -0.25V to VCC + 0.25V, enabling direct sensing of signals referenced to ground or above VCC.
The push-pull output stage delivers rail-to-rail swing under 8mA load, with VOH = 4.85V (min) and VOL = 0.4V (max) at VCC = 5V, while maintaining ultra-low quiescent current (11µA) and minimal supply-current surge during switching - critical for low-noise power domains in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V single supply - supports both 3V and 5V system rails without level-shifting. |
| Quiescent Current | 11µA per comparator - enables multi-year operation on coin-cell batteries in always-on sensing nodes. |
| Propagation Delay | 300ns at 100mV overdrive - ensures fast response for timing-critical zero-crossing and pulse-width detection. |
| Input Offset Voltage | ±0.5mV typical - provides high-precision threshold setting for <10mV resolution analog monitoring. |
| Common-Mode Input Range | -0.25V to VCC + 0.25V - allows direct interface to transducers and sensors operating below ground or above supply. |
| Output Drive Capability | Sinks and sources 8mA - drives LEDs, logic gates, or small MOSFET gates directly without buffer stages. |
| Input Bias Current | 1.0pA typical - minimizes loading error on high-impedance sensor sources like photodiodes or pH electrodes. |
Pinout & Package
MAX989EUA-TG069 is housed in an 8-pin µMAX package (package code U8+1), measuring 3mm × 3mm with exposed pad, RoHS-compliant and tape-and-reel packaged (TG069 suffix). The µMAX footprint is pin-compatible with industry-standard 8-pin SO and SOT23 dual-comparator layouts, enabling drop-in replacement in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Comparator A push-pull output - actively drives high/low to VCC/VEE; no external pull-up required. |
| 2 | INA− | Comparator A inverting input - accepts signals down to -0.25V, enabling ground-referenced or bipolar sensing. |
| 3 | INA+ | Comparator A noninverting input - matches INA− in voltage range and bias current (1pA). |
| 4 | VEE | Negative supply terminal - tied to ground in single-supply operation; supports dual-supply ±1.25V configurations. |
| 5 | VCC | Positive supply terminal - powers both comparators; PSRR of 55dB minimizes supply noise coupling. |
| 6 | INB+ | Comparator B noninverting input - electrically identical to INA+, enabling matched dual-threshold setups. |
| 7 | INB− | Comparator B inverting input - shares same ESD protection and input capacitance (1pF) as INA−. |
| 8 | OUTB | Comparator B push-pull output - independently controlled; supports window comparator or dual-signal monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O operation | Inputs accept -0.25V to VCC+0.25V; outputs swing within 400mV of rails at 8mA load - eliminates level-shifting ICs. |
| Ultra-low supply current | 11µA per comparator at +25°C - reduces total system standby current by >90% vs. standard comparators. |
| No phase reversal | Guaranteed stable output even when inputs exceed supply rails by 250mV - prevents false triggering in overvoltage events. |
| Internal hysteresis | ±3mV built-in - suppresses noise-induced oscillation on slow edges without external feedback components. |
| Low-propagation-delay consistency | 300ns typical at 100mV overdrive, varying <10% across -40°C to +85°C - enables deterministic timing in real-time control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7219M5X/NOPB | Higher supply current (32µA), slower propagation (500ns), open-drain output - requires external pull-up resistor. | Not suitable for rail-to-rail output swing without additional components; limited to 3V-only operation. | Select when cost sensitivity outweighs power/performance needs and board space allows pull-up resistor. |
| TLV3502IDR | Lower quiescent current (8.5µA), faster propagation (4.5ns), but input common-mode range limited to VEE to VCC–1.5V. | Cannot interface with signals below ground or above VCC; unsuitable for true rail-to-rail sensor front-ends. | Select only for high-speed digital thresholding where input range constraints are acceptable. |
Compared with LMV7219M5X/NOPB and TLV3502IDR, MAX989EUA-TG069 uniquely balances ultra-low power (11µA), rail-to-rail I/O flexibility, and robust 300ns timing - making it the only option among the three that supports ground-sensing, battery-monitoring, and zero-crossing detection in a single 8-pin µMAX package without external components.

FAQ
What is the operating temperature range for MAX989EUA-TG069?
The MAX989EUA-TG069 is fully specified and production-tested over the industrial temperature range of -40°C to +85°C. All electrical parameters - including propagation delay, input offset voltage, and supply current - are guaranteed across this range, ensuring reliable operation in automotive cabin modules, outdoor IoT sensors, and factory-floor equipment without derating.
Does MAX989EUA-TG069 require external hysteresis for noise immunity?
No, MAX989EUA-TG069 includes ±3mV internal hysteresis, which is sufficient to suppress chatter from typical PCB noise and slow-moving sensor signals. External hysteresis resistors are only needed when wider bands (>5mV) are required - for example, in high-noise motor-control feedback paths where the internal hysteresis may be insufficient.
Can MAX989EUA-TG069 operate from a single 3V supply?
Yes, MAX989EUA-TG069 operates from 2.5V to 5.5V single supply, making it fully compatible with 3V systems. At VCC = 3V, it maintains 300ns propagation delay (typical), 11µA supply current, and rail-to-rail output swing from 0V to 3V - enabling direct interface with 3V microcontrollers and ADC references without level translation.
What is the maximum capacitive load MAX989EUA-TG069 can drive on its output?
MAX989EUA-TG069's push-pull output is characterized up to 200pF load capacitance, with propagation delay increasing from 300ns (CL = 15pF) to 450ns (CL = 200pF) at VCC = 5V. For loads exceeding 200pF, external buffering is recommended to maintain timing integrity - especially in high-precision timing applications like phase-locked loop reference detection.
Is MAX989EUA-TG069 pin-compatible with other dual comparators in µMAX packages?
MAX989EUA-TG069 uses the standard 8-pin µMAX outline (package code U8+1) with identical pinout to industry-standard dual comparators such as MAX961 and LTC1540. However, functional compatibility requires verification of output stage type (push-pull vs. open-drain) and input voltage range - MAX989EUA-TG069's rail-to-rail inputs and push-pull outputs distinguish it from many µMAX-packaged alternatives.
