Product details
Overview
LMC6762AIMX/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with push-pull output, designed for ultra-low-power battery-operated systems. It delivers 10 μA max supply current per comparator, operates from 2.7V to 15V, and achieves rail-to-rail input common-mode range exceeding both supplies - enabling direct sensing near ground or V+ in 3V digital systems.
For engineers reviewing the LMC6762AIMX/NOPB datasheet, LMC6762AIMX/NOPB pinout, LMC6762AIMX/NOPB application, or LMC6762AIMX/NOPB equivalent, key selection criteria include guaranteed 2.7V operation, 420ns propagation delay at 100mV overdrive (5V), push-pull output eliminating external pull-ups, ±0.02pA input bias current, and SOIC-8 packaging compatible with space-constrained portable designs.
Technical Context
The LMC6762AIMX/NOPB implements a CMOS input stage with rail-to-rail common-mode voltage range extending beyond both supply rails - confirmed at 2.7V, 5V, and 15V - and features a fully complementary push-pull output stage capable of sourcing/sinking ≥30mA with <100mV saturation voltage swing. Its input offset voltage is specified up to 15mV (LMC6762AI grade), and temperature drift is limited to 2.0μV/°C.
This dual comparator uses independent internal biasing that maintains stable quiescent current across supply voltages (2.7–15V), with no dependency on VS; it supports single-supply operation down to 2.7V while ensuring full rail-to-rail input and output functionality - critical for precision threshold detection in low-voltage sensor interfaces and power monitoring circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMC6772AIMX/NOPB | Open-drain output instead of push-pull; otherwise identical specs including 10μA IS, rail-to-rail input, and 2.7–15V operation | Requires external pull-up for logic-high output; better suited for wired-OR bus configurations or level translation | Select LMC6772AIMX/NOPB only if open-drain functionality is required; LMC6762AIMX/NOPB preferred for direct logic interfacing |
| TLV3702IDR | Higher supply current (1.8μA typical per comparator vs. 10μA max), lower input offset (1.5mV max), but narrower supply range (2.7–16V) and no guaranteed 2.7V spec | Optimized for higher-precision, lower-noise applications where ultra-low power is secondary to accuracy | Choose TLV3702IDR when offset voltage <2mV is mandatory; LMC6762AIMX/NOPB remains optimal for cost-sensitive, battery-life-critical designs |
Compared with LMC6772AIMX/NOPB and TLV3702IDR, the LMC6762AIMX/NOPB uniquely balances guaranteed 2.7V operation, rail-to-rail input beyond supplies, push-pull output, and 10μA max supply current - making it the most suitable choice for long-life portable electronics requiring minimal external components.

FAQ
What is the maximum supply current specification for LMC6762AIMX/NOPB?
The LMC6762AIMX/NOPB has a maximum supply current of 10 μA per comparator under all operating conditions - verified across the full 2.7V to 15V supply range and −40°C to +85°C temperature range. This value represents the worst-case limit for both comparators active simultaneously, making LMC6762AIMX/NOPB suitable for multi-year battery operation in always-on monitoring systems.
Does LMC6762AIMX/NOPB support true rail-to-rail input operation?
Yes, LMC6762AIMX/NOPB supports rail-to-rail input common-mode voltage range exceeding both supply rails - confirmed at 2.7V, 5V, and 15V supplies. At V+ = 5V, the input range extends from −0.3V to +5.3V (CMRR > 55dB), enabling direct interface to signals below ground or above V+ without phase inversion - a capability explicitly validated in Figures 11-1 and 11-2 of the official datasheet.
What output architecture does LMC6762AIMX/NOPB use, and why does it matter?
LMC6762AIMX/NOPB uses a push-pull output stage, not open-drain. This means it actively drives both logic-high (to within 100mV of V+) and logic-low (to within 100mV of V−) without requiring external pull-up resistors. This architecture reduces component count, eliminates pull-up power loss, and ensures fast, deterministic logic transitions - critical for driving CMOS/TTL inputs directly in portable electronics.
Can LMC6762AIMX/NOPB operate reliably at 2.7V supply voltage?
Yes, LMC6762AIMX/NOPB is fully specified and ensured for operation at 2.7V - including propagation delay (420ns @ 100mV overdrive), input common-mode range (−0.3V to 3.0V), and output swing (2.5V high / 0.2V low @ 2.5mA load). This guarantee is explicitly stated in the "Operating Ratings" and "2.7V Electrical Characteristics" sections of the datasheet, confirming its suitability for single-cell Li-ion and 3V microcontroller systems.
What is the input bias current of LMC6762AIMX/NOPB, and how does it affect sensor interfacing?
The LMC6762AIMX/NOPB exhibits a typical input bias current of 0.02 pA - among the lowest available for dual comparators. This ultra-low value prevents loading errors in high-impedance sensor circuits (e.g., thermistors, pH electrodes, piezoelectric elements), preserving signal fidelity and enabling direct connection without buffer amplifiers. The datasheet confirms this performance across temperature and supply voltage variations.
