Product details
Overview
LMV761MAX from Texas Instruments is a single-channel, low-voltage precision comparator with push-pull output and active-low shutdown pin, operating from 2.7 V to 5.25 V supply. It delivers 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, 0.2 pA input bias current, and supports −40°C to +125°C ambient operation - ideal for battery-powered threshold detection in portable instrumentation.
For engineers reviewing the LMV761MAX datasheet, LMV761MAX pinout, LMV761MAX application, or LMV761MAX equivalent, key selection criteria include shutdown-enabled ultra-low quiescent current (275 μA typ), rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), push-pull output eliminating external pull-up resistors, and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV761MAX uses a CMOS input stage enabling femtoampere-level input bias current and high input impedance, allowing direct interfacing with high-resistance sensor networks and RC timing circuits without loading error. Its push-pull output stage drives logic-level loads directly without external components and sustains 4 mA sink/source capability at 5 V.
Shutdown functionality is implemented via an active-low SD pin with logic thresholds proportional to VCC, supporting mixed-voltage control (e.g., 5 V logic driving 2.7 V VCC). In shutdown mode, supply current drops to 20 nA and output enters high-impedance state - critical for power-gated subsystems in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - supports single-cell Li-ion and dual-cell alkaline battery systems without LDO pre-regulation. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures stable switching thresholds across automotive and industrial temperature ranges. |
| Propagation Delay | 120 ns at 50 mV overdrive - enables reliable high-speed sampling in ADC front-ends and digital line receivers. |
| Input Bias Current | 0.2 pA typical - permits use with >100 MΩ source impedances without significant offset drift or settling time penalty. |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply ripple and common-mode noise in noisy embedded environments like motor controllers. |
| Shutdown Supply Current | 20 nA - reduces system standby power by >99.9% versus active mode (275 μA), extending battery life in sleep-wake architectures. |
| Output Type | Push-pull - eliminates need for external pull-up resistor, simplifying BOM and improving rise/fall time symmetry (1.7/1.5 ns). |
Pinout & Package
LMV761MAX is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size. Pin 1 is N/C (not internally connected); pins 2–8 are functionally assigned as shown below:
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N/C | No internal connection - must be left floating or tied to ground per layout best practice; no electrical function. |
| 2 | −IN | Inverting input - accepts reference or feedback signal; high-impedance node sensitive to PCB trace capacitance. |
| 3 | +IN | Noninverting input - receives sensed signal; matched input capacitance to −IN minimizes dynamic offset during fast transitions. |
| 4 | V− | Negative power terminal - connects to ground or negative rail; serves as return path for all internal bias currents. |
| 5 | SDB | Shutdown (active low) - asserts shutdown when pulled ≤0.8 V; logic threshold scales with VCC; must not be left floating. |
| 6 | OUT | Digital output - push-pull structure sources/sinks up to 4 mA; compatible with TTL/CMOS logic families. |
| 7 | V+ | Positive power terminal - supplies internal circuitry; requires local 0.1 µF ceramic decoupling to minimize switching transients. |
| 8 | N/C | No internal connection - same as Pin 1; unused pad; no routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull output stage | Eliminates external pull-up resistor, reducing component count and ensuring symmetrical 1.7 ns rise / 1.5 ns fall times at 5 V. |
| Active-low shutdown (SDB) | Reduces supply current from 275 μA to 20 nA, enabling microamp-level system sleep modes in portable devices. |
| 0.2 pA input bias current | Enables direct interface with high-impedance sensors (e.g., photodiodes, pH electrodes) without gain error or drift. |
| 120 ns propagation delay | Supports ≥5 MHz sampling rates in window comparators and zero-crossing detectors for AC line monitoring. |
| −40°C to +125°C operation | Qualified for under-hood automotive and industrial control applications where thermal stability of switching thresholds is critical. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7215M5X | Single comparator, no shutdown pin; 1.8 V to 5.5 V supply; 1.2 mV max VOS; 130 ns tPD. | Lacks shutdown functionality - unsuitable for ultra-low-power wake-on-event designs requiring <100 nA standby. | Select when shutdown is unnecessary and wider supply range (1.8 V) is prioritized over offset voltage tightness. |
| TLV3601DBVR | Single comparator, no shutdown; 2.7 V to 5.5 V; 0.5 mV max VOS; 7 ns tPD; open-drain output. | Open-drain output requires external pull-up; faster but less drive strength than LMV761MAX's push-pull stage. | Select for nanosecond-speed applications where external pull-up is acceptable and lower propagation delay outweighs output flexibility. |
Compared with LMV7215M5X and TLV3601DBVR, the LMV761MAX uniquely combines shutdown capability, sub-millivolt offset, and push-pull output in an SOIC-8 package - making it optimal for battery-critical, thermally demanding, and layout-sensitive precision detection tasks.

FAQ
What is the maximum supply voltage rating for LMV761MAX?
The absolute maximum supply voltage (V+ – V−) for LMV761MAX is 5.5 V. Operation beyond this limit risks permanent damage. The recommended operating range is 2.7 V to 5.25 V, ensuring full specification compliance including input common-mode range, propagation delay, and output swing across temperature.
Does LMV761MAX support rail-to-rail input operation?
LMV761MAX supports input common-mode voltage from −0.3 V to (VCC − 1.3 V) at 5 V supply, and −0.3 V to 1.5 V at 2.7 V supply. While not fully rail-to-rail, this extended range accommodates signals near ground and leaves sufficient headroom for accurate comparison in single-supply systems.
How does the shutdown pin (SDB) behave during power-up?
The SDB pin of LMV761MAX must be actively driven high (≥2.0 V at 5 V VCC) to enable normal operation. If left floating during power-up, the output may enter an undefined state due to high-impedance input. TI recommends tying SDB to V+ through a pull-up resistor or controlling it with a known logic signal.
Can LMV761MAX drive a 50-pF capacitive load reliably?
Yes - LMV761MAX is characterized with 50-pF load in its 5-V switching characteristics table, delivering 1.7 ns rise time and 1.5 ns fall time. For loads >50 pF, output transition times increase linearly; layout best practices (short traces, local decoupling) are essential to maintain signal fidelity.
Is LMV761MAX qualified for automotive applications?
LMV761MAX itself is not AEC-Q100 qualified; only the LMV762Q-Q1 variant carries automotive qualification. However, LMV761MAX shares identical electrical specifications and operates across −40°C to +125°C, making it suitable for non-safety-critical automotive subsystems where full qualification is not mandated.
