Product details
Overview
LMV762MMX 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), making it suitable for battery-powered window comparators and high-speed line receivers.
For engineers reviewing the LMV762MMX datasheet, LMV762MMX pinout, LMV762MMX application, or LMV762MMX 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 VSSOP-8 package compatibility with space-constrained portable systems.
Technical Context
The LMV762MMX implements a CMOS-input, push-pull-output architecture optimized for single-supply operation. Its dual independent channels share no internal coupling, enabling simultaneous threshold detection with matched propagation delay skew ≤5 ns.
It features rail-to-rail input stage with 0.2 pA typical input bias current and 1 mV max input offset voltage over full temperature range, supporting precision analog-to-digital decision-making in low-power signal chains without input resistor matching constraints.
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 stable switching thresholds in automotive and industrial environments |
| Propagation Delay | 120 ns at 50 mV overdrive - supports >5 MHz digital sampling rates in timing-critical circuits |
| Supply Current per Channel | 300 μA typical at 5 V - allows dual-comparator operation within 1 mA total budget for ultra-low-power systems |
| CMRR / PSRR | 100 dB / 110 dB - rejects power supply noise and common-mode interference in noisy embedded environments |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Channel A output | Active-high/low push-pull output; sinks or sources up to ±4 mA at 5 V |
| 2 - −INA | Channel A inverting input | High-impedance CMOS node; 0.2 pA bias current enables high-Z sensor interfaces |
| 3 - +INA | Channel A noninverting input | Same electrical characteristics as −INA; supports differential or single-ended configurations |
| 4 - V− | Negative supply terminal | Ground reference for single-supply operation; must be connected to system GND |
| 5 - +INB | Channel B noninverting input | Independent of Channel A; enables dual-threshold or window comparator topologies |
| 6 - −INB | Channel B inverting input | Electrically isolated from Channel A inputs; supports asynchronous dual comparisons |
| 7 - OUTB | Channel B output | Functionally identical to OUTA; no cross-talk between outputs confirmed in datasheet |
| 8 - V+ | Positive supply terminal | Accepts 2.7–5.25 V; decoupling capacitor required per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull output stage | Eliminates external pull-up resistors, reducing component count and improving rise/fall time consistency (1.7 ns tr / 1.5 ns tf at 5 V) |

| Rail-to-rail input common-mode range | −0.3 V to VCC − 1.3 V - supports direct sensing of signals near ground or supply rails in single-supply systems |
| Low propagation delay skew | ≤5 ns between channels - ensures synchronized decision timing in dual-comparator applications like window detectors |
| Automotive qualification | AEC-Q100 Grade 1 certified (LMV762Q-Q1 variant); LMV762MMX shares identical die and VSSOP packaging |
Applications
| Portable Power Monitoring | Automotive Battery Management |
|---|---|
|
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 flag when cell voltage falls outside 3.0–4.2 V range. Use Value: 120 ns response ensures immediate shutdown on overvoltage/undervoltage events; 300 μA/channel minimizes quiescent drain on battery. |
Use Scenario: Supervising 12 V vehicle battery health across cold-crank, run, and sleep modes. IC Role / Device Role / Timing Role: One channel detects undervoltage (<10.5 V), second detects overvoltage (>15.5 V) using resistor-divider references. Use Value: −40°C to +125°C operation guarantees reliability under hood; 100 dB CMRR rejects alternator ripple noise. |
| High-Speed Line Receiver | Zero-Crossing Detector |
|
Use Scenario: Converting differential RS-422 signals to single-ended logic levels in industrial PLC backplanes. IC Role / Device Role / Timing Role: Dual comparator compares incoming data pair against mid-rail reference to reconstruct digital waveform. Use Value: 120 ns propagation delay supports >5 Mbps data rates; push-pull outputs drive 50 Ω transmission lines directly. |
Use Scenario: Detecting AC mains zero-crossing for phase-controlled dimming in smart lighting modules. IC Role / Device Role / Timing Role: Single channel biased at VCC/2 to trigger on sinusoidal input crossing reference point. Use Value: 0.2 mV offset voltage limits timing jitter to <1 μs; 110 dB PSRR prevents false triggers from supply ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3502IDR | 3.5 ns propagation delay, 65 μA supply current, open-drain output requiring pull-up | Better speed/power trade-off but lacks push-pull output and automotive temp range | Select when nanosecond timing dominates; add external pull-up and verify noise immunity |
| LMV7272MMX | 450 ns propagation delay, 110 μA supply current, same VSSOP-8 package and push-pull output | Lower performance grade; suited for cost-sensitive, non-automotive applications | Choose for legacy designs where 120 ns is unnecessary and BOM cost is critical |
Compared with TLV3502IDR and LMV7272MMX, the LMV762MMX uniquely balances sub-200 ns speed, true push-pull drive, and extended temperature capability - making it optimal for new automotive and portable designs demanding both precision and responsiveness.

FAQ
What is the maximum supply voltage rating for LMV762MMX?
The absolute maximum supply voltage (V+ – V−) for LMV762MMX is 5.5 V. Operation beyond this risks permanent damage. Recommended operating range is 2.7 V to 5.25 V per datasheet Section 6.4. Exceeding 5.25 V may cause parametric degradation or latch-up, especially at elevated temperatures. Always observe derating curves in thermal section 6.5 when operating near limits.
Does LMV762MMX support true rail-to-rail input operation?
LMV762MMX supports rail-to-rail input common-mode range from −0.3 V to VCC − 1.3 V, verified across −40°C to +125°C. It does not operate with inputs at exactly VCC or below −0.3 V, as CMRR drops below 50 dB outside that range. This enables direct interfacing with sensors referenced to ground or mid-supply, but not full VCC-to-GND coverage.
Can LMV762MMX be used in a window comparator configuration?
Yes - LMV762MMX is ideal for window comparators due to its dual independent channels, matched propagation delay (≤5 ns skew), and identical input specifications. Channel A monitors upper threshold, Channel B monitors lower threshold; their outputs feed logic gates to generate in-window or out-of-window flags. No internal crosstalk is specified, ensuring clean decision boundaries.
What is the output drive capability of LMV762MMX at 3.3 V supply?
At VCC = 3.3 V, LMV762MMX delivers VOH ≥ 3.0 V (VCC − 0.3 V) sinking 2 mA, and VOL ≤ 250 mV sourcing −2 mA, per 2.7-V Electrical Characteristics table. Output short-circuit current is ±6 mA minimum. These values ensure reliable interfacing with 3.3 V CMOS logic families without level translation.
Is LMV762MMX pin-compatible with LMV762DR (SOIC-8)?
No - LMV762MMX uses VSSOP-8 (3.00 mm × 3.00 mm), while LMV762DR uses SOIC-8 (4.90 mm × 3.91 mm). Pin functions are identical (OUTA, −INA, +INA, V−, +INB, −INB, OUTB, V+), but footprint and thermal characteristics differ. PCB redesign is required for substitution; thermal resistance is 235°C/W (VSSOP) vs 190°C/W (SOIC).
