Product details
Overview
LMV762MA/NOPB from Texas Instruments is a dual-channel, low-voltage, precision comparator with push-pull output, 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, and 300 μA supply current per channel. It operates from 2.7 V to 5.25 V and supports automotive-grade temperature range (−40°C to +125°C), enabling use in battery-powered sensor threshold detection circuits.
For engineers reviewing the LMV762MA/NOPB datasheet, LMV762MA/NOPB pinout, LMV762MA/NOPB application, or LMV762MA/NOPB equivalent, key selection criteria include its rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), CMRR of 100 dB, PSRR of 110 dB, and absence of external pull-up requirement due to integrated push-pull output stage.
Technical Context
The LMV762MA/NOPB implements a CMOS-input, push-pull-output architecture optimized for single-supply operation. Its dual independent comparators share no internal coupling, and each features identical electrical characteristics including 0.2 pA typical input bias current and 1 mV max input offset voltage over full temperature range.
It lacks shutdown functionality-unlike the LMV761 or LMV762Q-Q1 variants-and is specified only for SOIC-8 packaging. The device does not support differential output or hysteresis internally; external resistor networks are required for hysteresis implementation per application requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - supports direct interface with 3.3 V and 5 V logic systems without level shifting |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - enables accurate threshold detection in precision analog monitoring |
| Propagation Delay | 120 ns at 50 mV overdrive - suitable for high-speed sampling and zero-crossing detection up to ~4 MHz |
| Supply Current per Channel | 300 μA typical at 5 V - allows dual-comparator operation in ultra-low-power portable systems |
| CMRR / PSRR | 100 dB / 110 dB - rejects power supply noise and common-mode interference in noisy industrial environments |
| Output Type | Push-pull - eliminates need for external pull-up resistor, reducing BOM count and board space |

Pinout & Package
LMV762MA/NOPB is supplied in an 8-pin SOIC package (body size 4.90 mm × 3.91 mm) with standard JEDEC MS-012AC footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Channel A output | Active push-pull digital output; sinks or sources current without external pull-up |
| 2 - −INA | Channel A inverting input | High-impedance CMOS node; accepts signals down to −0.3 V below V− |
| 3 - +INA | Channel A noninverting input | High-impedance CMOS node; supports rail-to-rail common-mode input range |
| 4 - V− | Negative supply terminal | Ground reference for single-supply operation; must be connected to system GND |
| 5 - +INB | Channel B noninverting input | Independent high-Z input; electrically isolated from Channel A inputs |
| 6 - −INB | Channel B inverting input | Independent high-Z input; no internal connection to Channel A |
| 7 - OUTB | Channel B output | Independent push-pull output; fully decoupled from OUTA |
| 8 - V+ | Positive supply terminal | Accepts 2.7–5.25 V; requires local 0.1 µF ceramic bypass to V− |
Key Features
| Feature | Design Value |
|---|---|
| Precision offset performance | 0.2 mV typical VOS, 1 mV max over −40°C to +125°C - ensures stable trip points across automotive and industrial thermal cycles |

| Single-supply push-pull output | No external pull-up required - simplifies PCB layout, reduces component count, and improves rise/fall time consistency |
| High noise immunity | 100 dB CMRR and 110 dB PSRR - maintains decision integrity in mixed-signal systems with switching regulators or motor drivers |
| Fast response with low power | 120 ns propagation delay at 300 μA per channel - delivers timing-critical decisions without compromising energy budget |
Applications
| Portable Battery Monitoring | Industrial Sensor Threshold Detection |
|---|---|
|
Use Scenario: Real-time monitoring of Li-ion cell voltage during charge/discharge cycles in handheld medical devices. IC Role / Device Role / Timing Role: Dual comparator configured as window detector to assert fault flags when voltage falls below 3.0 V or exceeds 4.25 V. Use Value: 0.2 mV offset and 120 ns delay enable precise, fast-response battery protection without microcontroller intervention. |
Use Scenario: Detecting overtemperature conditions from RTD or thermistor bridges in PLC I/O modules. IC Role / Device Role / Timing Role: One channel compares bridge output to upper trip point; second channel compares to lower trip point for hysteresis-enabled alarm latching. Use Value: 0.2 pA input bias avoids loading high-resistance sensor bridges; push-pull outputs drive optocouplers directly. |
| Automotive Cabin Climate Control | High-Speed Line Receiver |
|
Use Scenario: Converting analog cabin temperature and humidity signals into digital control signals for HVAC actuator drivers. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous comparison against calibrated thresholds to generate discrete fan speed and damper position commands. Use Value: AEC-Q100 Grade 1 qualification (via LMV762Q-Q1 family lineage) and 125°C ambient rating ensure reliability in under-dash environments. |
Use Scenario: Reconstructing differential data streams from RS-422 or LVDS receivers in test equipment front-ends. IC Role / Device Role / Timing Role: Configured as high-speed differential line receiver with external resistive termination and hysteresis for noise margin. Use Value: 120 ns propagation delay and 100 dB CMRR allow clean digital recovery from sub-100 mV differential signals in EMI-prone lab settings. |
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; higher thermal resistance (235°C/W vs 190°C/W) | Better suited for space-constrained PCBs; requires tighter layout control for thermal management | Select when board area is critical and thermal derating can be accommodated. |
| TLV3502IDR | 3.5 ns propagation delay, 65 μA supply current, rail-to-rail input, but only 1.8–5.5 V supply range and no guaranteed 125°C operation | Higher speed and lower power, but unqualified for extended temperature automotive use | Prefer for consumer-grade high-speed applications where ambient stays ≤85°C. |
Compared with LMV762MA/NOPB, LMV762MM/NOPB offers identical performance in a smaller footprint at the cost of thermal margin, while TLV3502IDR trades precision offset stability and temperature range for raw speed and ultra-low quiescent current - making each suitable for distinct thermal, size, and timing constraints.

FAQ
What is the maximum operating temperature for LMV762MA/NOPB?
The LMV762MA/NOPB is rated for continuous operation from −40°C to +125°C ambient temperature, meeting industrial and extended-temperature automotive requirements. This specification is validated per TI's recommended operating conditions and thermal derating guidelines in the SNOS998I datasheet.
Does LMV762MA/NOPB include a shutdown pin?
No, LMV762MA/NOPB does not feature a shutdown pin. Unlike the LMV761 (single with SD) or LMV762Q-Q1 (automotive dual), this variant is a fixed-function dual comparator with no power-management control input. Power reduction must be achieved externally via supply gating.
Can LMV762MA/NOPB operate from a 2.5-V supply?
No - LMV762MA/NOPB has a minimum recommended supply voltage of 2.7 V per the datasheet's Recommended Operating Conditions table. Operation at 2.5 V falls outside guaranteed specifications and may result in degraded propagation delay, reduced output swing, or increased offset voltage.
What is the input common-mode voltage range for LMV762MA/NOPB?
At 5 V supply, the input common-mode voltage range is −0.3 V to 3.8 V (VCC − 1.3 V); at 2.7 V supply, it is −0.3 V to 1.5 V. This rail-to-rail capable input stage allows direct sensing of signals near ground or near VCC without level-shifting circuitry.
Is LMV762MA/NOPB pin-compatible with other LMV762 variants?
Yes - LMV762MA/NOPB (SOIC-8), LMV762MM/NOPB (VSSOP-8), and LMV762Q-Q1 (SOIC/VSSOP) share identical pin functions and assignments per the "Pin Functions for SOIC and VSSOP (Dual)" table in SNOS998I. Mechanical footprint differs, but electrical connectivity and layout logic are preserved.
