Product details
Overview
LMV762MMX/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 - used in high-speed differential line receivers and window comparators operating from 2.7 V to 5.25 V single supply.
For engineers reviewing the LMV762MMX/NOPB datasheet, LMV762MMX/NOPB pinout, LMV762MMX/NOPB application, or LMV762MMX/NOPB equivalent, this page delivers verified electrical specs, SOIC-8 package mapping, automotive-grade alternatives, and design-critical timing behavior under real load and temperature conditions.
Technical Context
The LMV762MMX/NOPB implements two independent CMOS-input comparators in a single SOIC-8 package, each featuring rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V) and push-pull output stage eliminating external pull-up resistors. Its architecture supports fast decision-making in battery-powered systems where quiescent current and input bias current (0.2 pA typical) must be minimized.
It operates across −40°C to +125°C with guaranteed 1 mV max input offset voltage over temperature, 100 dB CMRR, and 110 dB PSRR - enabling stable threshold detection in noisy industrial or automotive environments without trimming. No shutdown pin is present, distinguishing it from the LMV761 and LMV762Q-Q1 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - compatible with Li-ion, 3.3 V, and 5 V logic rails without level shifting |
| Propagation Delay | 120 ns at 50 mV overdrive - enables >5 MHz sampling in high-speed analog-to-digital front ends |
| Input Offset Voltage | 0.2 mV typ / 1 mV max over −40°C to +125°C - ensures accurate threshold detection without calibration |
| Supply Current per Channel | 300 µA at 5 V - allows dual-comparator operation in ultra-low-power portable devices |
| Input Bias Current | 0.2 pA typical - permits use with >100 MΩ feedback networks and high-impedance sensors |
| Output Type | Push-pull - drives logic inputs directly; no external pull-up required, reducing BOM count and board area |
| CMRR / PSRR | 100 dB / 110 dB - rejects power supply noise and common-mode interference in mixed-signal PCBs |
Pinout & Package
LMV762MMX/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm body size), optimized for automated assembly and thermal performance (RθJA = 190°C/W). The device has no shutdown pin and is pin-compatible with standard dual-comparator footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Channel A push-pull output - sinks or sources up to ±4 mA; logic-level compatible |
| 2 | −INA | Channel A inverting input - accepts signals down to −0.3 V (beyond rail) with 0.2 pA bias |
| 3 | +INA | Channel A noninverting input - same high-impedance, rail-to-rail CMVR as −INA |
| 4 | V− | Negative power terminal - connects to ground or negative rail; shared by both channels |
| 5 | +INB | Channel B noninverting input - electrically isolated from Channel A; identical specs |
| 6 | −INB | Channel B inverting input - supports independent reference comparison per channel |
| 7 | OUTB | Channel B push-pull output - fully independent; no crosstalk or shared drive limitations |
| 8 | V+ | Positive power terminal - supplies both comparators; decoupling required at pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | CMVR extends to −0.3 V and up to VCC − 1.3 V - enables direct sensing of signals near supply rails |
| Push-pull output | Eliminates need for external pull-up resistor - reduces component count, layout complexity, and rise-time uncertainty |
| Low input bias current | 0.2 pA typical - preserves accuracy in high-Z sensor interfaces (e.g., photodiode, thermopile) |
| Fast propagation delay | 120 ns at 50 mV overdrive - supports precise edge detection in digital encoders and motor commutation |
| High PSRR/CMRR | 110 dB PSRR and 100 dB CMRR - maintains threshold stability despite supply ripple or EMI coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV762Q-Q1 | AEC-Q100 Grade 1 qualified; HBM ESD rated to ±2000 V; identical electrical specs and SOIC/VSSOP footprint | Required for automotive ECUs; supports extended ambient range (−40°C to +125°C) with full qualification documentation | Select LMV762Q-Q1 when automotive safety compliance (ISO 26262 readiness) or enhanced ESD robustness is mandatory |
| TLV3502IDR | Faster propagation delay (4.5 ns typ), higher supply current (1.3 mA/ch), no rail-to-rail input - CMVR limited to (V−) + 0.2 V to (V+) − 0.2 V | Better suited for ultra-high-speed clock/data recovery; unsuitable for low-voltage sensor monitoring near rails | Choose TLV3502IDR only when speed >10× faster than LMV762MMX/NOPB is critical and input range constraints are acceptable |
Compared with LMV762MMX/NOPB, LMV762Q-Q1 adds automotive qualification without sacrificing performance or footprint, while TLV3502IDR trades precision rail-to-rail input and ultra-low power for raw speed - making LMV762MMX/NOPB optimal for cost-sensitive industrial and portable designs requiring balanced speed, accuracy, and efficiency.

FAQ
What is the maximum operating supply voltage for LMV762MMX/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV762MMX/NOPB is 5.5 V. However, the recommended operating range is 2.7 V to 5.25 V per the datasheet's Recommended Operating Conditions table. Exceeding 5.25 V may degrade long-term reliability or cause parametric shift, especially at elevated temperatures. LMV762MMX/NOPB must not be operated beyond 5.5 V under any condition.
Does LMV762MMX/NOPB include a shutdown function?
No, LMV762MMX/NOPB does not have a shutdown pin. Unlike the LMV761 (single with SD) or LMV762Q-Q1 (dual automotive variant with optional SD in VSSOP), the LMV762MMX/NOPB is a fixed-function dual comparator with no enable/disable control. Power must be managed externally if low-quiescent operation is required between active periods.
What is the input common-mode voltage range for LMV762MMX/NOPB at 5 V supply?
At VCC = 5 V, the input common-mode voltage range (CMVR) for LMV762MMX/NOPB is −0.3 V to 3.8 V, specified for CMRR > 50 dB. This rail-to-rail capable input allows direct interfacing with sensors and DACs operating near ground or near VCC, unlike many comparators that require headroom on both rails.
Can LMV762MMX/NOPB drive a 50-pF capacitive load reliably?
Yes - LMV762MMX/NOPB is characterized with CL = 50 pF in its 5-V switching characteristics table, showing 120 ns propagation delay and 1.5 ns fall time. Its push-pull output delivers sufficient drive strength (±4 mA) to maintain signal integrity into 50-pF loads without external buffering, provided proper 0.1-μF ceramic decoupling is placed at V+ and V− pins.
Is LMV762MMX/NOPB RoHS-compliant and lead-free?
Yes, LMV762MMX/NOPB carries the "/NOPB" suffix, which Texas Instruments designates as lead-free and RoHS-compliant. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard Pb-free reflow profiles. Full compliance documentation is available in TI's official product folder and packaging reports.
