Product details
Overview
LMC6772AIMMX/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with open-drain outputs, designed for ultra-low-power battery-operated systems. It delivers 10 μA max supply current per comparator, operates from 2.7 V to 15 V, and supports rail-to-rail input common-mode voltage range exceeding both supply rails - enabling direct sensing near ground or V+ in single-supply applications such as portable metering and handheld electronics.
For engineers reviewing the LMC6772AIMMX/NOPB datasheet, LMC6772AIMMX/NOPB pinout, LMC6772AIMMX/NOPB application, or LMC6772AIMMX/NOPB equivalent, key selection criteria include micropower operation (<25 μA total), open-drain output flexibility (up to 15 V pull-up), rail-to-rail input capability at 2.7 V, propagation delay of 420 ns (100 mV overdrive, 5 V supply), and −40°C to +85°C industrial temperature rating.
Technical Context
The LMC6772AIMMX/NOPB integrates two independent high-impedance CMOS comparators with rail-to-rail input stages and open-drain NMOS outputs. Its input stage achieves <0.02 pA typical input bias current and 75 dB common-mode rejection, enabling precision threshold detection in low-current sensor interfaces. The open-drain architecture supports wired-OR logic and level-shifting across voltage domains up to 15 V, independent of the comparator's own supply.
It features built-in short-circuit protection (40 mA sink limit) and operates reliably down to 2.7 V with guaranteed rail-to-rail input range - including 200 mV beyond V− and V+ - making it suitable for low-voltage monitoring where input signals may exceed supply rails without phase inversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | Max 25 μA total (both comparators, 25°C), enabling multi-year battery life in always-on monitoring circuits. |
| Supply Voltage Range | 2.7 V to 15 V - supports single-cell Li-ion (3.0–4.2 V), 5 V logic, and 12 V industrial rails without level shifting. |
| Input Common-Mode Range | Exceeds V− by 0.2 V and V+ by 0.2 V (min) - allows direct interface to sensors or signals outside supply rails. |
| Propagation Delay | 420 ns (low-to-high, 100 mV overdrive, 5 V supply) - sufficient for RC timers, window comparators, and multivibrator clock generation. |
| Output Type | Open-drain NMOS - enables flexible pull-up to any voltage ≤15 V and wired-OR configuration for alarm aggregation. |
| Input Offset Voltage | Max 8 mV (LMC6772AI grade, 25°C) - ensures stable switching thresholds in precision voltage monitoring. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended-temperature portable equipment environments. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-drain output of Comparator A - requires external pull-up; sinks up to 40 mA. |
| 2 | IN− A | Inverting input of Comparator A - rail-to-rail capable, <0.02 pA bias current. |
| 3 | IN+ A | Non-inverting input of Comparator A - same rail-to-rail and impedance specs as IN− A. |
| 4 | V− | Negative supply terminal - common ground or negative rail for dual-supply operation. |
| 5 | IN+ B | Non-inverting input of Comparator B - electrically identical to IN+ A. |
| 6 | IN− B | Inverting input of Comparator B - matches IN− A in performance and voltage range. |
| 7 | OUT B | Open-drain output of Comparator B - independently configurable; supports wired-OR with OUT A. |
| 8 | V+ | Positive supply terminal - accepts 2.7 V to 15 V; powers both comparators and internal bias circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Supports input signals 200 mV beyond V− and V+, eliminating need for external level-shifting in single-supply sensor monitoring. |
| Ultra-low quiescent current | 25 μA max total supply current enables >10-year battery life in coin-cell-powered IoT endpoints and wearables. |
| Open-drain output architecture | Allows output pull-up to 15 V regardless of V+ (e.g., 3.3 V supply driving 5 V logic), simplifying mixed-voltage system interfacing. |
| Short-circuit protected output | 40 mA current limit prevents latch-up or damage during transient faults - critical for robust alarm and safety-critical monitoring. |
| Wide supply voltage range | 2.7 V minimum enables direct use with single Li-ion or alkaline cells; 15 V maximum supports industrial 12 V rail compatibility. |
Applications
| Portable Power Monitoring | Logic-Level Translation |
|---|---|
|
Use Scenario: Real-time battery voltage supervision in handheld medical devices, detecting low-battery thresholds before shutdown. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel monitors upper threshold (e.g., 4.1 V), the other lower (e.g., 3.0 V). Use Value: Rail-to-rail inputs sense full battery range without external resistive dividers; 10 μA per comparator extends operational runtime between charges. |
Use Scenario: Interfacing 1.8 V microcontroller GPIO to 5 V peripheral control lines in compact IoT gateways. IC Role / Device Role / Timing Role: Comparator used as unidirectional level shifter - input referenced to 1.8 V logic, output pulled to 5 V via external resistor. Use Value: Open-drain output eliminates level-shifter ICs or MOSFETs; wide supply range allows shared 3.3 V V+ while pulling output to 5 V. |
| RC-Based Timing Circuits | Alarm Aggregation |
|
Use Scenario: Generating precise time delays in portable test equipment using resistor-capacitor networks. IC Role / Device Role / Timing Role: Comparator configured as monostable multivibrator - input trigger initiates capacitor charge/discharge cycle. Use Value: 420 ns propagation delay ensures sub-microsecond timing accuracy; low supply current minimizes timing drift due to supply variation. |
Use Scenario: Consolidating multiple fault signals (over-temperature, over-voltage, motion detection) into a single interrupt line for MCU. IC Role / Device Role / Timing Role: Wired-OR connection of both open-drain outputs to shared pull-up - any active fault pulls line low. Use Value: Eliminates discrete diodes or OR-gate ICs; rail-to-rail inputs accept diverse sensor reference voltages without signal conditioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6762AIMMX/NOPB | Push-pull output (vs. open-drain); otherwise identical specs (10 μA, rail-to-rail input, 2.7–15 V). | Requires no external pull-up; unsuitable for wired-OR or level-shifting above V+. | Select when driving CMOS loads directly and avoiding external components; avoid when interfacing mixed-voltage domains. |
| TLV3702IDGKR | Lower supply current (1.8 μA/ch), but narrower supply range (2.7–16 V), no guaranteed rail-to-rail input beyond rails. | Better for ultra-long-life applications; less tolerant of input overvoltage in sensor front-ends. | Prefer for energy-harvesting or coin-cell systems where every nanoamp matters; verify input common-mode margin for your sensor signal swing. |
Compared with LMC6772AIMMX/NOPB, LMC6762AIMMX/NOPB offers simplified drive but loses level-shifting flexibility, while TLV3702IDGKR reduces power consumption significantly but sacrifices guaranteed rail-exceeding input range - making LMC6772AIMMX/NOPB optimal for robust, mixed-voltage, battery-powered monitoring where signal integrity at supply extremes is critical.

FAQ
What is the maximum supply voltage for LMC6772AIMMX/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC6772AIMMX/NOPB is 16 V, with recommended operating range of 2.7 V to 15 V. Exceeding 16 V risks permanent damage. At 15 V operation, the device maintains rail-to-rail input range and 420 ns propagation delay under 100 mV overdrive - confirmed in TI's SNOS749G datasheet Section 5.4.
Does LMC6772AIMMX/NOPB support true rail-to-rail input beyond the supply rails?
Yes - LMC6772AIMMX/NOPB guarantees input common-mode voltage range extending at least 0.2 V beyond both V− and V+ (e.g., −0.2 V to 5.2 V at 5 V supply), as specified in Section 5.3 and 5.4 of the datasheet. This enables direct interface to sensors or signals that exceed supply rails without output phase inversion, a key advantage over standard comparators.
Can LMC6772AIMMX/NOPB outputs drive a 12 V logic load?
Yes - the open-drain NMOS output of LMC6772AIMMX/NOPB can be pulled up to any voltage ≤15 V, independent of its own supply voltage. For example, with V+ = 3.3 V, an external 12 V pull-up resistor enables direct 12 V logic-level output, as detailed in Section 3 (Description) and Figure 6-4 (Universal Logic Level Shifter) of the datasheet.
What is the temperature range for LMC6772AIMMX/NOPB?
LMC6772AIMMX/NOPB is rated for −40°C to +85°C junction temperature, corresponding to the LMC6772AI grade per Section 5.2 of the datasheet. This industrial temperature range is validated across all electrical specifications, including input offset voltage (max 8 mV) and supply current (max 25 μA), ensuring reliability in portable and embedded environments.
Is LMC6772AIMMX/NOPB pin-compatible with other variants in the family?
Yes - LMC6772AIMMX/NOPB uses the VSSOP-8 (DGK) package and shares identical pinout with LMC6772AIMM/NOPB, LMC6772QMMX/NOPB, and all other VSSOP-packaged LMC6772 variants. Pin functions (OUT A, IN− A, IN+ A, V−, IN+ B, IN− B, OUT B, V+) are consistent across grades, enabling drop-in replacement within the same package footprint.
