Product details
Overview
MAX976ESA+TG069 from Maxim Integrated is a dual, high-speed, low-power comparator optimized for +3V/+5V single-supply operation in space-constrained systems. It delivers 20ns propagation delay, 225µA supply current per comparator, and rail-to-rail output swing without external pull-ups-enabling direct interface with CMOS/TTL logic in battery-powered threshold detection circuits.
For engineers reviewing the MAX976ESA+TG069 datasheet, MAX976ESA+TG069 pinout, MAX976ESA+TG069 application, or MAX976ESA+TG069 equivalent, key selection criteria include shutdown capability (not supported), input common-mode range extending 200mV below ground, ±2mV input offset voltage, and guaranteed performance over –40°C to +85°C.
Technical Context
The MAX976ESA+TG069 implements a CMOS-based dual comparator architecture with internal hysteresis (0.5–4.0mV input-referred) to suppress noise-induced oscillation during slow input transitions. Its push-pull output stage drives rail-to-rail under 2mA load while tolerating continuous short-circuit faults to either supply rail.
Input-stage design supports a common-mode voltage range of –0.2V to (VCC – 1.2V), allowing ground-sensing operation independent of VCC level. Propagation delay matching between channels is ±1ns, and skew is ≤2ns-critical for timing-sensitive dual-channel applications like window comparators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 20ns typical at 50mV overdrive - enables sub-50MHz signal edge detection in digital line receivers. |
| Supply Current | 225µA per comparator - supports multi-comparator designs in 3V battery-powered systems with <1mA total quiescent draw. |
| Input Offset Voltage | ±2mV max at +25°C - ensures accurate 10mV-level threshold discrimination without calibration. |
| Common-Mode Range | –0.2V to (VCC – 1.2V) - permits direct sensing of signals referenced to system ground in single-supply 3V/5V rails. |
| Output Drive | Rail-to-rail swing sinking/sourcing 2mA - eliminates need for external pull-up resistors when interfacing with 3.3V/5V logic families. |
| PSRR / CMRR | 63dB / 66dB min - maintains stable trip points despite supply ripple or common-mode noise in noisy industrial environments. |
| Hysteresis | 0.5–4.0mV input-referred - prevents chatter on slowly varying inputs such as IR photodiode outputs or temperature sensor ramps. |
Pinout & Package
MAX976ESA+TG069 is housed in an 8-pin SO package (SOIC-8, 150mil width), RoHS-compliant with lead-free finish (+ suffix). Pin mapping is validated per Maxim's official pin description table and top-marking convention "MAX976ESA+".
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA– | Inverting input for comparator A - accepts signals down to –0.2V, enabling ground-referenced threshold detection. |
| 2 | INA+ | Noninverting input for comparator A - used with external reference or sensor feedback for precise level comparison. |
| 3 | OUTA | Push-pull output for comparator A - drives CMOS/TTL loads directly; no external pull-up required. |
| 4 | GND | Analog/digital ground reference - must connect to low-impedance PCB ground plane to maintain noise immunity. |
| 5 | GND | Second ground connection - reduces ground bounce in dual-comparator operation; ties to same net as Pin 4. |
| 6 | OUTB | Push-pull output for comparator B - independent switching enables window or dual-threshold architectures. |
| 7 | INB+ | Noninverting input for comparator B - allows separate signal conditioning paths for each channel. |
| 8 | VCC | Single supply input (2.7V–5.5V) - requires local 0.1µF ceramic decoupling capacitor placed adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Single-Supply Operation | Functions from 2.7V to 5.5V - eliminates need for split supplies in portable 3V systems or mixed-voltage industrial controllers. |
| Ground-Sensing Inputs | Common-mode range extends 200mV below GND - enables direct interface with sensors whose outputs swing below ground (e.g., thermocouples, current shunts). |
| Rail-to-Rail Outputs | Drives full VCC–GND swing with 2mA load - ensures reliable logic-level compatibility with 3.3V and 5V microcontrollers without level-shifting. |
| Internal Hysteresis | 0.5–4.0mV input-referred - suppresses false triggering on noisy or slowly changing analog inputs without external components. |
| Short-Circuit Tolerance | Continuous fault protection to either rail - enhances reliability in field-deployed equipment subject to wiring errors or ESD events. |
Applications
| Battery-Powered Threshold Detector | IR Receiver Front-End |
|---|---|
Use Scenario: Monitoring battery voltage against undervoltage lockout (UVLO) and overvoltage protection (OVP) thresholds in handheld medical devices. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - INA+/INA– and INB+/INB– compare sensed voltage against precision reference to generate independent UVLO/OVP flags. Use Value: 20ns propagation delay ensures rapid response to sudden battery faults; 225µA/quiescent current extends runtime in always-on monitoring modes. |
Use Scenario: Converting modulated infrared photodiode current into clean digital pulses for remote control decoding in consumer electronics. IC Role / Device Role / Timing Role: High-speed comparator amplifying weak, noisy IR signal - one channel processes raw photodiode output; second channel provides adaptive threshold via peak-detect feedback. Use Value: Ground-sensing inputs accept negative-going transients from photodiode bias networks; rail-to-rail output directly clocks 3.3V logic without pull-ups. |
| Digital Line Receiver | 3V Industrial Sensor Interface |
Use Scenario: Recovering TTL/CMOS-compatible data from long traces or unterminated cables in PLC I/O modules. IC Role / Device Role / Timing Role: Comparator restoring degraded logic edges - differential input configuration rejects common-mode noise; hysteresis cleans jittery transitions. Use Value: 66dB CMRR rejects coupled noise on shared backplanes; 20ns delay preserves data integrity up to 25Mbps NRZ signaling. |
Use Scenario: Interfacing 0–10V analog sensors (e.g., pressure transducers) to 3V microcontroller ADCs with programmable alarm thresholds. IC Role / Device Role / Timing Role: Level-shifting comparator translating industrial voltage ranges to 3V logic levels - inputs tolerate –0.2V to 4.3V at VCC = 5V, enabling safe 10V sensor input handling. Use Value: Input common-mode range beyond supply rails avoids external attenuation; ±2mV offset ensures <1% error in 200mV threshold settings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Slower 1.3µs propagation delay; no internal hysteresis; open-collector output requiring pull-up. | Suitable only for low-speed DC thresholding; cannot replace MAX976ESA+TG069 in IR receivers or digital line recovery. | Select only if cost sensitivity outweighs speed, power, and interface requirements. |
| TLV3501CDR | Faster 4.5ns delay but higher 5.2mA supply current; rail-to-rail input (not ground-sensing); no shutdown mode. | Better for ultra-high-speed sampling but unsuitable for battery life-critical or ground-referenced sensor inputs. | Choose when nanosecond timing dominates; avoid where sub-µA standby or –0.2V input capability is required. |
Compared with LM393DR and TLV3501CDR, MAX976ESA+TG069 uniquely balances 20ns speed, 225µA efficiency, ground-sensing inputs, and rail-to-rail CMOS/TTL compatibility-making it optimal for compact, battery-aware industrial and consumer sensing nodes.

FAQ
What is the operating supply voltage range for MAX976ESA+TG069?
The MAX976ESA+TG069 operates from a single supply of +2.7V to +5.5V. This range supports both 3V battery-powered systems and standard 5V industrial rails. Absolute maximum rating is +6V, but sustained operation above 5.5V risks permanent damage. Performance specifications-including propagation delay and input offset-are guaranteed across the full –40°C to +85°C temperature range within this supply window.
Does MAX976ESA+TG069 support shutdown mode?
No, MAX976ESA+TG069 does not include a shutdown function. Shutdown capability is exclusive to the MAX998 variant (e.g., MAX998EUT+T), which features a dedicated SHDN pin and reduces supply current to 1nA in disabled state. The MAX976ESA+TG069 draws 225µA per comparator continuously and lacks any enable/disable control pin or internal power-gating circuitry.
What is the input common-mode voltage range of MAX976ESA+TG069?
The input common-mode voltage range of MAX976ESA+TG069 is specified as –0.2V to (VCC – 1.2V). This means it can accurately compare signals referenced below ground-such as those from current-sense amplifiers or photodiodes-while maintaining correct output logic states. For example, at VCC = 3.3V, inputs may swing from –0.2V to +2.1V; at VCC = 5.0V, the upper limit extends to +3.8V.
Can MAX976ESA+TG069 drive TTL or CMOS logic directly?
Yes, MAX976ESA+TG069 can drive TTL and CMOS logic directly due to its rail-to-rail push-pull output stage. It sources and sinks up to 2mA while maintaining VOH ≥ VCC – 0.4V and VOL ≤ 0.4V, meeting standard 3.3V and 5V logic thresholds. No external pull-up resistors are needed-unlike open-collector comparators-reducing BOM count and board area in dense layouts.
How does internal hysteresis improve performance in MAX976ESA+TG069?
MAX976ESA+TG069 incorporates 0.5–4.0mV of input-referred hysteresis to prevent output oscillation when input voltages hover near the trip point-a common issue with noisy or slowly varying signals like IR photodiode outputs or thermal sensor ramps. This built-in hysteresis eliminates the need for external positive-feedback resistors, simplifying design while ensuring clean, chatter-free switching even under marginal signal conditions.
