Product details
Overview
LMV762QMMX/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 is qualified for automotive applications (AEC-Q100 Grade 1, −40°C to +125°C ambient).
For engineers reviewing the LMV762QMMX/NOPB datasheet, LMV762QMMX/NOPB pinout, LMV762QMMX/NOPB application, or LMV762QMMX/NOPB equivalent, this device supports high-speed differential line reception, window detection, zero-crossing sensing, and battery-powered system monitoring where rail-to-rail input range, low quiescent current, and no external pullup are critical.
Technical Context
The LMV762QMMX/NOPB integrates two independent comparators with CMOS inputs and complementary push-pull outputs-eliminating need for external pullup resistors. Each channel features 100 dB CMRR and 110 dB PSRR, enabling stable operation in noisy single-supply environments.
It supports true single-supply operation down to 2.7 V with input common-mode range extending 0.3 V below V− and up to V+ − 1.3 V. The device lacks shutdown functionality (unlike LMV761), and its VSSOP-8 package provides compact layout for space-constrained automotive and portable designs.
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 temperature range |
| Propagation Delay | 120 ns at 50 mV overdrive - supports >5 MHz sampling in high-speed timing circuits |
| Supply Current per Channel | 450 μA typical at 5 V - balances speed and power for always-on battery monitoring |
| Input Bias Current | 0.2 pA typical - permits use of megaohm-level resistor dividers without error contribution |
| Output Type | Push-pull - drives logic loads directly; no external pullup required, reducing BOM count and board area |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply and common-mode noise in EMI-prone automotive environments |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm body size), thermally enhanced for automotive reliability; pin-compatible with SOIC-8 but with 45% smaller footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Channel A output | Active-high/low push-pull output; sinks or sources up to ±4 mA at 5 V |
| −INA | Channel A inverting input | High-impedance CMOS node; accepts signals down to V− − 0.3 V |
| +INA | Channel A noninverting input | High-impedance CMOS node; supports rail-to-rail common-mode range |
| V− | Negative supply terminal | Ground reference for single-supply operation; must be connected to system GND |
| +INB | Channel B noninverting input | Independent high-Z input; electrically isolated from Channel A |
| −INB | Channel B inverting input | Independent high-Z input; enables dual-threshold or differential pair configurations |
| OUTB | Channel B output | Fully independent push-pull output; no crosstalk or shared drive limitations |
| V+ | Positive supply terminal | Accepts 2.7–5.25 V; decoupling capacitor required between V+ and V− |
Key Features

| 0.2 pA input bias current | Enables high-impedance sensor interfacing (e.g., thermistors, photodiodes) without offset drift |
| 120 ns propagation delay | Supports real-time response in motor commutation feedback and overvoltage latch circuits |
| 100 dB CMRR | Maintains accuracy in presence of ground bounce or supply ripple on shared PCB planes |
Applications
| Automotive Battery Monitoring | High-Speed Line Receiver |
|---|---|
Use Scenario: Real-time detection of 12 V battery undervoltage (e.g., <10.5 V) and overvoltage (>15.5 V) conditions in engine control units. IC Role / Device Role / Timing Role: Dual comparator configured as window detector; one channel monitors upper threshold, the other lower threshold. Use Value: Enables fail-safe shutdown before battery damage occurs; 1 mV max VOS ensures ±50 mV threshold accuracy over full temperature range. |

| Portable Medical Sensor Interface | Zero-Crossing Detector for AC Mains |
Use Scenario: Amplified ECG or pulse oximeter signal conditioning where ultra-low input current prevents electrode polarization errors. IC Role / Device Role / Timing Role: Precision comparator comparing analog sensor output against programmable reference to trigger ADC sampling. Use Value: 0.2 pA input bias avoids DC error in high-impedance electrode paths; 300 μA/channel enables multi-day battery life in wearable devices. |
Use Scenario: Detecting AC line zero crossings for phase-controlled dimmers or solid-state relays in smart home controllers. IC Role / Device Role / Timing Role: Comparator with rail-to-rail input swing detecting when mains-derived sine wave crosses 0 V reference. Use Value: Input common-mode range extends to V− − 0.3 V allows direct GND-referenced sensing; push-pull output drives microcontroller GPIO without pullup. |
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 | Same electrical specs, but SOIC-8 package (4.90 mm × 3.91 mm); higher thermal resistance (190°C/W vs 235°C/W) | Suitable for industrial PCBs with less stringent space constraints; not AEC-Q100 qualified | Select when automotive qualification is unnecessary and board area is not limiting. |
| TLV3502IDR | Lower propagation delay (4.5 ns), but higher supply current (1.2 mA/ch); no AEC-Q100 qualification; different pinout | Better for ultra-high-speed sampling (>100 MSPS), but unsuitable for automotive or low-power portable use | Choose only if speed outweighs power and qualification requirements. |
Compared with LMV762QMMX/NOPB, LMV762MM/NOPB trades automotive qualification and compact size for easier hand-soldering and legacy compatibility, while TLV3502IDR offers nanosecond-speed tradeoffs at significantly higher power and no automotive validation.

FAQ
What is the operating temperature range for the LMV762QMMX/NOPB?
The LMV762QMMX/NOPB is AEC-Q100 Grade 1 qualified, with guaranteed operation from −40°C to +125°C ambient temperature. Electrical specifications-including input offset voltage, propagation delay, and supply current-are ensured across this full range, making it suitable for under-hood automotive applications and industrial edge devices.
Does the LMV762QMMX/NOPB include a shutdown feature?
No, the LMV762QMMX/NOPB does not include a shutdown pin. Unlike the LMV761 (single-channel) or LMV762 variants with shutdown, the LMV762QMMX/NOPB is a dual comparator with fixed operation-no SD pin is present. Power control must be implemented externally via supply switching if needed.
What package type is used for the LMV762QMMX/NOPB?
The LMV762QMMX/NOPB uses an 8-pin VSSOP package (DGK) with nominal body dimensions of 3.00 mm × 3.00 mm. This thermally enhanced, surface-mount package supports automated assembly and provides better power dissipation than SOT-23 while occupying significantly less board area than SOIC-8.
Can the LMV762QMMX/NOPB operate from a 3.3 V supply?
Yes, the LMV762QMMX/NOPB is fully specified for operation from 2.7 V to 5.25 V. At 3.3 V, it maintains 120 ns propagation delay (typical), 0.2 mV typical input offset voltage, and 300 μA supply current per channel-enabling seamless integration into modern 3.3 V microcontroller-based systems without level translation.
Is the LMV762QMMX/NOPB pin-compatible with other LMV762 variants?
The LMV762QMMX/NOPB shares identical pin functions with the LMV762MM/NOPB (SOIC-8) and LMV762MME/NOPB (VSSOP-8), but differs from LMV761 variants due to dual-channel architecture and absence of shutdown. Pin mapping matches the standard dual-comparator VSSOP/SOIC convention: OUTA, −INA, +INA, V−, +INB, −INB, OUTB, V+.
