Product details
Overview
LMC6762AIM/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with push-pull output, designed for ultra-low-power sensing and threshold-detection circuits. It delivers 10 μA max supply current per comparator, operates from 2.7V to 15V, achieves rail-to-rail input common-mode range exceeding both supplies, and provides rail-to-rail output swing within 100 mV of rails at 2.7V/2.5 mA - enabling direct logic interfacing in battery-powered metering and handheld electronics.
For engineers reviewing the LMC6762AIM/NOPB datasheet, LMC6762AIM/NOPB pinout, LMC6762AIM/NOPB application, or LMC6762AIM/NOPB equivalent, key selection considerations include its guaranteed 2.7V operation, <15 mV input offset voltage (AI grade), 420 ns propagation delay at 100 mV overdrive (5V), push-pull output eliminating external pull-ups, and SOIC-8 packaging compatible with space-constrained portable designs.
Technical Context
The LMC6762AIM/NOPB implements two independent high-impedance CMOS comparators with input stages biased for sub-10 μA quiescent current per channel, independent of supply voltage. Its rail-to-rail input stage uses complementary PMOS/NMOS differential pairs to extend common-mode range beyond V− by 0.3 V and above V+ by 0.3 V - verified at 2.7V, 5V, and 15V supplies.
The push-pull output stage integrates complementary NMOS/PMOS drivers capable of sourcing/sinking ≥2.5 mA while maintaining VOH ≥2.4 V and VOL ≤0.4 V at 2.7V, and includes internal short-circuit protection limiting output current to 40 mA - with thermal derating guidance for continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 12 μA typical / 20 μA max per comparator at 2.7V - enables multi-year battery life in always-on monitoring circuits |
| Input Offset Voltage | 5 mV max (AI grade) at 25°C - ensures reliable detection of small analog signals without trimming |
| Propagation Delay | 420 ns max (low-to-high) at 100 mV overdrive, V+ = 5V - supports kHz-range timing and zero-crossing detection |
| Input Common-Mode Range | Extends 0.3 V beyond V− and V+ rails - allows direct sensing of signals near ground or supply in single-supply systems |

| 7 | Output B | Push-pull CMOS output; electrically isolated from Output A; no crosstalk observed |
| 8 | V+ | Positive supply terminal; operates from 2.7 V to 15 V; supplies both comparators |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Valid common-mode range from −0.3 V to V+ + 0.3 V - enables direct connection to transducers operating near supply rails |
| Push-pull output architecture | No external pull-up required - reduces BOM count and PCB area in portable logic interface designs |
| Ultra-low supply current | 20 μA max per comparator across full 2.7–15 V range - eliminates supply regulation overhead in energy-harvesting nodes |
| Guaranteed 2.7 V operation | Full AC/DC specs ensured at 2.7 V - supports Li-ion single-cell and 3 V microcontroller systems without voltage boost |
| Low input bias current | 0.02 pA typical at 2.7 V - prevents loading of high-impedance sensors (e.g., pH electrodes, piezoresistive elements) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6772AIM/NOPB | Open-drain output instead of push-pull; otherwise identical specs and pinout | Requires external pull-up for logic-level output; better suited for wired-OR bus configurations | Select when level translation or bus arbitration is needed; avoid if minimizing external components is critical |
| TLV3702IDR | Higher supply current (1.8 μA per comparator), lower offset (1.5 mV max), but narrower input common-mode range (to V+ − 0.1 V) | Not suitable for signals near V+ in single-supply systems; optimized for precision over ultra-low power | Choose for higher accuracy where 10× higher current budget is acceptable; verify rail-to-rail input requirement |
Compared with LMC6762AIM/NOPB, LMC6772AIM/NOPB offers identical micropower performance but requires external pull-up infrastructure, while TLV3702IDR trades 10× higher current for improved offset and speed - making LMC6762AIM/NOPB optimal for true ultra-low-power, rail-to-rail input, and minimal-BOM designs.

FAQ
What is the maximum supply voltage rating for the LMC6762AIM/NOPB?
The LMC6762AIM/NOPB has an absolute maximum supply voltage (V+ − V−) of 16 V, with recommended operating range from 2.7 V to 15 V. Operation above 15 V risks permanent damage; the device is fully specified and characterized across the 2.7–15 V range, including propagation delay, offset voltage, and output swing parameters.
Does the LMC6762AIM/NOPB support true rail-to-rail input operation?
Yes, the LMC6762AIM/NOPB supports true rail-to-rail input operation: its input common-mode voltage range extends to −0.3 V below V− and up to V+ + 0.3 V, verified at 2.7 V, 5 V, and 15 V supplies. This allows direct interfacing with signals near ground or the positive rail without level-shifting circuitry - a key advantage in single-supply battery systems.
Can the LMC6762AIM/NOPB drive CMOS logic directly without a pull-up resistor?
Yes, the LMC6762AIM/NOPB features a push-pull CMOS output stage that actively drives both high and low states, enabling direct connection to CMOS and TTL logic inputs without external pull-up resistors. At 2.7 V supply and 2.5 mA load, it guarantees VOH ≥ 2.4 V and VOL ≤ 0.4 V - meeting standard logic threshold requirements.
What is the input offset voltage specification for the LMC6762AIM/NOPB?
The LMC6762AIM/NOPB (AI grade) has a maximum input offset voltage of 5 mV at 25°C and 2.7 V supply, with typical value of 3 mV. Over temperature (−40°C to +85°C), the max remains 8 mV. This is confirmed in Section 7 of the datasheet and ensures reliable detection of analog signals above ~10 mV without calibration.
Is the LMC6762AIM/NOPB pin-compatible with other comparators in the LMC67xx family?
Yes, the LMC6762AIM/NOPB is pin-compatible with LMC6762BIM/NOPB (higher offset grade) and LMC6772AIM/NOPB (open-drain variant). All share identical SOIC-8 pinout and electrical connections; only output stage topology differs between LMC6762 and LMC6772. No PCB redesign is needed when substituting within this family.
