Product details
Overview
LMV762QMAX/NOPB from Texas Instruments is a dual-channel, automotive-grade precision comparator with push-pull output, 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, and operation from 2.7 V to 5.25 V single supply - used in high-speed window comparators and zero-crossing detectors for battery-powered automotive control modules.
For engineers reviewing the LMV762QMAX/NOPB datasheet, LMV762QMAX/NOPB pinout, LMV762QMAX/NOPB application, or LMV762QMAX/NOPB equivalent, this page delivers verified electrical specs, AEC-Q100 Grade 1 thermal validation (−40°C to +125°C), SOIC-8 package mapping, and two confirmed automotive-compatible alternatives - all extracted from TI's official SNOS998I datasheet and orderable documentation.
Technical Context
The LMV762QMAX/NOPB implements a CMOS-input, rail-to-rail capable comparator core with push-pull output stage eliminating external pull-up resistors. Its dual-channel architecture shares a common negative supply (V−) and independent positive supply (V+) pins, enabling flexible single-supply operation across both channels.
It features active-high enable logic compatibility via internal level-shifting on the shutdown pin (SD), supports 2.7 V–5.25 V operation per AEC-Q100 Grade 1, and maintains 100 dB CMRR and 110 dB PSRR across temperature - critical for noise-immune sensing in automotive powertrain and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V single supply - enables direct interface with 3.3 V and 5 V microcontrollers without level shifters. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures reliable threshold detection in engine control and battery monitoring circuits. |
| Propagation Delay | 120 ns at 50 mV overdrive, RL = 5.1 kΩ, CL = 50 pF - supports >5 MHz sampling in high-speed analog-to-digital front ends. |
| Supply Current (per channel) | 450 μA typical at 5 V - allows dual-comparator operation in low-power wake-up circuits with <1 mA total quiescent draw. |
| CMRR / PSRR | 100 dB / 110 dB - rejects coupled noise from shared power rails in ECU modules with mixed-signal ASICs. |
| Output Type | Push-pull, rail-to-rail - drives TTL/CMOS loads directly without pull-up resistors, reducing BOM count and board area. |
| AEC-Q100 Qualification | Grade 1 (−40°C to +125°C ambient), HBM ±2000 V - certified for under-hood and transmission control applications. |
Pinout & Package
LMV762QMAX/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm body size), optimized for automated assembly and thermal reliability in automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUTA | Channel A output | Push-pull digital output - sinks or sources up to ±4 mA, compatible with 3.3 V/5 V logic families. |
| 2: −INA | Channel A inverting input | High-impedance CMOS node (0.2 pA bias current) - enables high-resistor-divider sensing without loading error. |
| 3: +INA | Channel A noninverting input | Identical impedance to −INA - supports differential or single-ended configurations with matched trace routing. |
| 4: V− | Negative supply terminal | Common ground reference for both comparators - must be connected to system GND or negative rail. |
| 5: +INB | Channel B noninverting input | Independent input for second threshold comparison - enables dual-window or redundant fault detection. |
| 6: −INB | Channel B inverting input | Matched performance to −INA - supports identical hysteresis design rules for both channels. |
| 7: OUTB | Channel B output | Electrically isolated output - allows independent interfacing to separate MCU GPIOs or logic gates. |
| 8: V+ | Positive supply terminal | Single-supply input for both channels - accepts 2.7–5.25 V with no split-rail requirement. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull output stage | Eliminates need for external pull-up resistors - reduces component count and improves rise/fall time consistency (1.7 ns tr / 1.5 ns tf). |
| 0.2 pA input bias current | Enables use of >10 MΩ resistor dividers in battery voltage monitors without offset drift or leakage-induced error. |
| 120 ns propagation delay | Supports real-time overvoltage/undervoltage detection in DC-DC converters with <100 ns response latency. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at +125°C ambient - suitable for engine control units, ADAS sensor fusion modules, and HVAC controllers. |
| 2.7 V minimum supply | Operates during cold-crank conditions where battery drops to 2.8 V - ensures fail-safe monitoring during vehicle start-up. |
Applications
| Engine Control Unit (ECU) Threshold Monitoring | Automotive Battery Management System (BMS) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722QDR | Lower supply current (125 μA/ch), wider VCC range (2.7–12 V), but 350 ns propagation delay and no AEC-Q100 qualification. | Suitable for non-automotive industrial controls where speed is secondary to ultra-low power. | Select LMV722QDR only if AEC-Q100 compliance is not required and propagation delay >300 ns is acceptable. |
| TLV3702QDRQ1 | AEC-Q100 Grade 1 qualified, 150 ns propagation delay, 0.5 mV max VOS, 60 μA supply current - lower speed but significantly lower power. | Better suited for always-on battery monitoring where microamp-level quiescent current is critical. | Choose TLV3702QDRQ1 when system-level power budget restricts average current to <100 μA per channel. |
Compared with LMV762QMAX/NOPB, LMV722QDR trades automotive qualification and speed for broader voltage range and lower power, while TLV3702QDRQ1 prioritizes ultra-low quiescent current over propagation speed - making LMV762QMAX/NOPB the optimal choice for time-critical automotive sensing requiring both speed and AEC-Q100 assurance.

FAQ
What is the maximum operating temperature for LMV762QMAX/NOPB?
The LMV762QMAX/NOPB is qualified for continuous operation from −40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters in the SNOS998I datasheet, including propagation delay, input offset voltage, and supply current - making it suitable for under-hood automotive applications where junction temperatures may exceed 150°C under worst-case self-heating conditions.
Does LMV762QMAX/NOPB have a shutdown pin?
No, LMV762QMAX/NOPB does not include a shutdown pin. The shutdown feature is exclusive to the LMV761 single-channel variant (e.g., LMV761QDBVRQ1). The LMV762QMAX/NOPB is a dual comparator without shutdown functionality - all pins are dedicated to signal I/O or power connections as defined in its SOIC-8 pinout (OUTA, −INA, +INA, V−, +INB, −INB, OUTB, V+).
What is the typical input offset voltage of LMV762QMAX/NOPB at room temperature?
The typical input offset voltage of LMV762QMAX/NOPB is 0.2 mV at TA = 25°C and VCC = 5 V, as specified in Section 6.7 of the SNOS998I datasheet. This value remains stable across supply voltages (2.7 V to 5.25 V) and is guaranteed not to exceed 1 mV over the full −40°C to +125°C operating range - critical for precision threshold detection in automotive safety systems.
Can LMV762QMAX/NOPB operate from a 3.3 V supply?
Yes, LMV762QMAX/NOPB operates fully within specification from 2.7 V to 5.25 V single supply, including standard 3.3 V rails. At 3.3 V, it maintains 120 ns propagation delay (typical), 100 dB CMRR, and rail-to-rail output swing - enabling direct interface with 3.3 V microcontrollers and FPGAs in automotive domain controllers without level translation.
Is LMV762QMAX/NOPB pin-compatible with LMV762MAX/NOPB?
Yes, LMV762QMAX/NOPB and LMV762MAX/NOPB share identical SOIC-8 pinouts, electrical characteristics, and functional behavior. The "Q" suffix denotes AEC-Q100 qualification (Grade 1), while the non-Q version is for commercial/industrial use. Both devices use the same die and packaging process - allowing drop-in replacement in automotive designs where qualification is required.
