Product details
Overview
LMV762MA from Texas Instruments is a dual-channel, low-voltage precision comparator with push-pull output, designed for single-supply operation from 2.7 V to 5.25 V. It delivers 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, and 300 µA total supply current (both channels), enabling high-speed threshold detection in space-constrained portable systems.
For engineers reviewing the LMV762MA datasheet, LMV762MA pinout, LMV762MA application, or LMV762MA equivalent, key selection criteria include its rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), 100 dB CMRR, 110 dB PSRR, push-pull output eliminating external pull-ups, and AEC-Q100 Grade 1 qualification for automotive ambient temperature operation up to +125°C.
Technical Context
The LMV762MA integrates two independent comparators sharing a common V+ and V− supply, each featuring CMOS inputs with 0.2 pA typical bias current and a push-pull output stage capable of sourcing 6 mA and sinking 40 mA at 5 V. Its internal architecture supports precise differential sensing without hysteresis circuitry, requiring external feedback for noise immunity.
It operates across −40°C to +125°C with guaranteed 1 mV max input offset voltage over temperature and maintains stable propagation delay skew ≤5 ns between channels. The device lacks shutdown functionality-unlike the LMV761-making it suitable for always-on, low-latency decision circuits where channel independence and timing consistency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - Enables direct interface with 3.3 V and 5 V logic rails without level shifting. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - Ensures accurate threshold detection across automotive and industrial temperature extremes. |
| Propagation Delay | 120 ns at 50 mV overdrive, 5 V supply - Supports >5 MHz sampling rates in high-speed window comparators or zero-crossing detectors. |
| CMRR / PSRR | 100 dB / 110 dB - Rejects power supply ripple and common-mode noise in noisy embedded environments. |
| Output Drive | Push-pull, no external pull-up required - Reduces BOM count and PCB area; sinks 40 mA at 5 V for direct LED or logic interface. |
| Input Bias Current | 0.2 pA typical - Allows use with megaohm-level resistor dividers and femtofarad-level timing capacitors without error drift. |
| Operating Temperature | −40°C to +125°C - Qualified per AEC-Q100 Grade 1 for under-hood automotive and industrial control applications. |
Pinout & Package
LMV762MA is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size, optimized for automated assembly and thermal performance (RθJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUTA | Channel A output | Active-high/low push-pull output; drives directly to logic or load without external components. |
| 2: −INA | Channel A inverting input | Differential input node; accepts signals down to −0.3 V (beyond rail) for wide dynamic range sensing. |
| 3: +INA | Channel A noninverting input | Differential input node; supports common-mode voltages up to VCC − 1.3 V at 5 V supply. |
| 4: V− | Negative power terminal | Ground reference for single-supply operation; must be connected to system GND. |
| 5: +INB | Channel B noninverting input | Independent second comparator input; electrically isolated from Channel A except via shared supplies. |
| 6: −INB | Channel B inverting input | Second differential input pair; enables dual-threshold or differential line receiver configurations. |
| 7: OUTB | Channel B output | Independent push-pull output; skew ≤5 ns vs OUTA ensures synchronized dual decisions. |
| 8: V+ | Positive power terminal | Primary supply input; accepts 2.7–5.25 V; requires local 0.1 µF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull output stage | Eliminates need for external pull-up resistors, reducing component count and improving rise/fall time consistency (1.7 ns rise, 1.5 ns fall at 5 V). |
| Low input offset voltage | 0.2 mV typical, 1 mV max over full temperature range - enables sub-millivolt threshold accuracy in battery monitoring or sensor interfaces. |
| Ultra-low input bias current | 0.2 pA typical - permits high-impedance signal sources (e.g., photodiodes, thermistors) without loading-induced errors. |
| High-speed switching | 120 ns propagation delay with 5 ns inter-channel skew - supports real-time dual-comparator functions like window detection or phase comparison. |
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C ambient operation with HBM ESD ≥±2000 V - meets automotive electronics reliability requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV762MM/NOPB | VSSOP-8 package (3.00 mm × 3.00 mm); identical electrical specs and pinout; higher thermal resistance (RθJA = 235°C/W). | Better suited for ultra-compact PCBs where SOIC footprint is prohibitive; less optimal for high-power-density layouts due to thermal limits. | Select LMV762MM/NOPB when board area is constrained and thermal dissipation <100 mW; otherwise LMV762MA offers superior thermal performance. |
| TLV3502IDR | Single-channel, 4.5 ns propagation delay, 65 µA supply current; no AEC-Q100 qualification; different pinout (SOIC-8 but non-compatible). | Targeted at ultra-low-power, high-speed single-comparator roles-not a drop-in replacement for dual-channel or automotive use. | Choose TLV3502IDR only for new designs prioritizing speed/power over channel count or automotive compliance; not suitable for LMV762MA replacement. |
Compared with LMV762MM/NOPB, LMV762MA provides lower thermal resistance and proven manufacturability in SOIC-8 assembly lines; versus TLV3502IDR, it offers dual-channel integration and automotive qualification at the cost of higher quiescent current-critical for functional safety and system consolidation.

FAQ
What is the maximum operating supply voltage for LMV762MA?
The absolute maximum supply voltage (V+ – V−) for LMV762MA is 5.5 V. However, the recommended operating range is 2.7 V to 5.25 V per the datasheet. Operating above 5.25 V risks violating safe operating area limits and may degrade long-term reliability, especially at elevated temperatures. LMV762MA is not rated for 6 V or higher continuous operation.
Does LMV762MA include a shutdown feature?
No, LMV762MA does not include a shutdown pin. Unlike the LMV761 (single-channel variant), the LMV762MA dual comparator lacks an SD terminal. All functionality remains active whenever V+ and V− are powered within specification. This design choice prioritizes deterministic latency and eliminates wake-up delays in always-on monitoring applications.
What is the input common-mode voltage range for LMV762MA at 5 V supply?
At V+ = 5 V, the input common-mode voltage range for LMV762MA is −0.3 V to 3.7 V (VCC − 1.3 V), specified for CMRR > 50 dB. This allows inputs to extend 300 mV below ground and operate near the positive rail-enabling direct interfacing with transducers and sensors that swing beyond standard supply rails without clamping diodes.
Can LMV762MA drive a 50 Ω transmission line directly?
LMV762MA is not designed for direct 50 Ω line driving. Its push-pull output can sink up to 40 mA and source up to 6 mA at 5 V, corresponding to ~83 Ω minimum resistive load for full swing. Driving 50 Ω continuously would exceed safe output current limits and cause excessive self-heating. Use a dedicated line driver IC or series termination for impedance-matched high-speed signaling.
Is LMV762MA pin-compatible with LMV762Q-Q1?
Yes, LMV762MA (SOIC-8) and LMV762Q-Q1 (SOIC-8) share identical pinout, electrical specifications, and package dimensions. The LMV762Q-Q1 adds AEC-Q100 Grade 1 qualification and enhanced ESD robustness (HBM ±2000 V), while LMV762MA meets industrial-grade requirements. Both are functionally interchangeable in non-automotive designs, though LMV762Q-Q1 is required for automotive production.
