Product details
Overview
LMV792MM/NOPB from Texas Instruments is a dual, low-noise, CMOS-input operational amplifier optimized for low-voltage, precision sensor signal conditioning. It delivers 5.8 nV/√Hz input voltage noise, 17 MHz unity-gain bandwidth, and rail-to-rail output swing within 25 mV of rails at 10 kΩ load - enabling high-fidelity photodiode amplification and medical front-end designs operating from 1.8 V to 5.5 V supplies.
For engineers reviewing the LMV792MM/NOPB datasheet, LMV792MM/NOPB pinout, LMV792MM/NOPB application, or LMV792MM/NOPB equivalent, key selection criteria include its femtoampere-level input bias current (100 fA), shutdown mode consuming only 0.02 µA per channel, and guaranteed performance across −40°C to +125°C for industrial and automotive-sensing systems.
Technical Context
The LMV792MM/NOPB integrates two independent amplifiers in a single 10-pin VSSOP package, each with dedicated enable (EN A/EN B) pins supporting independent power gating. Its CMOS input stage enables ground-sensing operation and ultra-low input current, while the rail-to-rail output stage uses positive feedback to sustain >40 mA sourcing capability even at 1.8 V supply.
It operates stably at unity gain with 17 MHz GBW and exhibits <0.01% THD+N at 1 kHz into 600 Ω, making it suitable for active filters and low-distortion buffering where supply headroom is constrained. Shutdown transition times are specified as 110 ns turn-on and 800 ns turn-off at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 5.8 nV/√Hz at 1 kHz - enables high-SNR amplification of microvolt-level sensor signals |
| Unity-Gain Bandwidth | 17 MHz - supports wideband active filtering and fast-settling instrumentation |
| Supply Current (per channel) | 1.30 mA in enable mode - balances speed and battery life in portable devices |
| Shutdown Current (per channel) | 0.02 µA - extends battery runtime in duty-cycled sensing nodes |
| Rail-to-Rail Output Swing | 25 mV from rail at 10 kΩ - maximizes dynamic range in 1.8–5.5 V single-supply systems |
| Input Bias Current | 100 fA - preserves signal integrity in high-impedance photodiode and pH electrode interfaces |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
LMV792MM/NOPB is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 179.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Amplifier A output | Delivers rail-to-rail buffered signal; capable of sourcing 45 mA at 5 V |
| IN A− (Pin 2) | Inverting input A | High-impedance CMOS node; accepts differential or single-ended feedback |
| IN A+ (Pin 3) | Noninverting input A | Ground-referenced input; supports single-supply sensor biasing |
| V− (Pin 4) | Negative supply rail | Reference for both amplifiers; connects to GND in single-supply configurations |
| EN A (Pin 5) | Enable control A | Logic-high (>4.6 V at 5 V supply) activates Amp A; <0.4 V disables |
| EN B (Pin 6) | Enable control B | Independent gating for Amp B; enables channel-level power management |
| IN B+ (Pin 7) | Noninverting input B | Dedicated input for second channel; electrically isolated from Amp A |
| IN B− (Pin 8) | Inverting input B | Supports independent feedback networks per channel |
| OUT B (Pin 9) | Amplifier B output | Matches OUT A specs; allows dual-path signal processing without cross-talk |
| V+ (Pin 10) | Positive supply rail | Accepts 1.8–5.5 V; powers both amplifiers and enable logic |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise CMOS input | 5.8 nV/√Hz + 100 fA bias current enables direct interfacing with high-Z sensors without guard rings |
| Independent dual-channel shutdown | Separate EN A/EN B pins allow asymmetric power sequencing - e.g., keep Amp A active while disabling Amp B during idle cycles |
| Rail-to-rail output with 60 mA drive | Sustains 25 mV swing into 10 kΩ and drives 600 Ω loads - eliminates need for external buffers in data-acquisition front ends |
| Guaranteed 1.8 V operation | Full AC/DC specs validated down to 1.8 V - supports direct connection to Li-ion battery discharge curves |
| −40°C to +125°C qualification | Specified over full industrial temperature range with no derating - suitable for engine control and motor-drive feedback paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376IDGKR | Lower noise (4.5 nV/√Hz), higher supply current (750 µA/channel), no shutdown | Better SNR in static precision systems; unsuitable for battery-cycled operation | Select when lowest possible noise dominates over power; avoid if shutdown functionality is required |
| AD8602ARZ-REEL7 | Higher input bias current (1 pA), no enable pins, wider offset range (±1.5 mV) | Cost-optimized general-purpose dual op-amp; lacks rail-to-rail output swing at light loads | Choose for non-critical industrial controls where shutdown and ultra-low bias are not needed |
Compared with OPA2376IDGKR and AD8602ARZ-REEL7, LMV792MM/NOPB uniquely combines femtoampere input bias, integrated shutdown, and guaranteed 1.8 V operation - making it the only option among the three qualified for battery-powered, high-impedance sensor nodes requiring extended temperature range support.

FAQ
What is the maximum supply voltage for LMV792MM/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV792MM/NOPB is 6 V. Recommended operating conditions specify a range of 1.8 V to 5.5 V, with full electrical characteristics ensured at both 2.5 V and 5 V supplies. Operation above 5.5 V risks permanent damage and voids warranty compliance.
Does LMV792MM/NOPB support true rail-to-rail input?
No, LMV792MM/NOPB does not support rail-to-rail input. Its input common-mode voltage range extends to the negative rail (V−) but only to (V+ – 1.2 V) on the high side. However, it does provide rail-to-rail output swing - within 25 mV of either rail at 10 kΩ load - which is explicitly confirmed in the datasheet's 5-V Electrical Characteristics table.
What is the typical turn-on time for LMV792MM/NOPB in shutdown mode?
The typical turn-on time for LMV792MM/NOPB is 110 ns at 5 V supply, measured from enable pin crossing the threshold (VEN ≥ 4.6 V) to output settling within 1% of final value. This fast wake-up enables use in burst-mode sensing applications where latency must remain below 200 ns.
Can LMV792MM/NOPB drive a 600 Ω load effectively?
Yes, LMV792MM/NOPB is specified to drive 600 Ω loads with ≤0.01% THD+N at 1 kHz and delivers rail-to-rail output swing within 45 mV of either rail under that condition. Its output stage sources up to 60 mA and sinks up to 21 mA at 5 V, ensuring stable operation into low-impedance loads without external buffering.
Is LMV792MM/NOPB pin-compatible with other dual op-amps in VSSOP-10 packages?
No, LMV792MM/NOPB is not pin-compatible with generic dual op-amps in VSSOP-10. Its pinout includes dedicated enable inputs (Pins 5 and 6) and nonstandard input ordering (IN A− on Pin 2, IN A+ on Pin 3). Substitution requires PCB layout revision unless replacing another LMV792 variant.
