Product details
Overview
LMV932MM/NOPB from Texas Instruments is a dual rail-to-rail input/output (RRIO) operational amplifier optimized for 1.8-V operation, delivering 1.4-MHz gain bandwidth, 100-μA per-channel supply current, and output swing within 80 mV of the rails into 600-Ω load - enabling precision signal conditioning in space-constrained, battery-powered systems such as wearable health monitors and portable medical sensors.
For engineers reviewing the LMV932MM/NOPB datasheet, LMV932MM/NOPB pinout, LMV932MM/NOPB application, or LMV932MM/NOPB equivalent, this page provides verified specifications, package mapping to VSSOP-8, functional context for low-voltage sensor front-ends and battery monitoring circuits, and validated alternative options for design continuity.
Technical Context
The LMV932MM/NOPB implements a CMOS-input RRIO architecture with input common-mode range extending 200 mV beyond both supply rails and output stage capable of driving 600-Ω loads with minimal ringing. Its 101-dB DC open-loop gain and 5.5-mV max input offset voltage support high-accuracy DC-coupled amplification at ultra-low supply voltages.
Designed for single-supply operation from 1.8 V to 5.5 V, it maintains stable phase margin (≥67°) and 0.35 V/μs slew rate across voltage rails, while its 123-dB amplifier-to-amplifier isolation prevents crosstalk in dual-channel configurations used for differential sensing or active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration into single-cell Li-ion (2.7–4.2 V) and two-cell alkaline (2.4–3.2 V) systems without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer or 10× gain amplification up to ~140 kHz for ECG front-end or audio preamp stages. |
| Input Offset Voltage (max) | 5.5 mV - ensures ≤0.55% full-scale error in 1-V reference-based battery voltage monitoring at room temperature. |
| Supply Current per Channel | 103–205 μA - allows continuous operation for >1 year on a 200-mAh coin cell in always-on wearable sensor nodes. |
| Output Swing (600 Ω load) | Within 80 mV of rails at 1.8 V - preserves dynamic range in low-voltage ADC interfaces (e.g., 12-bit SAR with 1.8-V reference). |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - permits direct sensing of signals below ground or above supply, critical for biopotential electrode biasing. |
| CMRR / PSRR | Min 50 dB (CMRR), 70 dB (PSRR) - suppresses supply ripple and common-mode noise in noisy portable environments. |
Pinout & Package
LMV932MM/NOPB is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm, optimized for high-density PCB layouts in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or feedback network; rail-to-rail swing supports full utilization of ADC input range. |
| 2 | −IN A | Inverting input of channel A - connects to feedback resistor in inverting configuration or sensor bridge leg in differential setup. |
| 3 | +IN A | Noninverting input of channel A - accepts low-impedance sensor signal or reference voltage; accepts inputs down to −0.2 V relative to V−. |
| 4 | V− | Negative supply terminal - tied to GND in single-supply use; must be decoupled with 100-nF ceramic capacitor near pin. |
| 5 | V+ | Positive supply terminal - accepts 1.8–5.5 V; requires local 100-nF bypass cap to minimize supply-induced noise coupling. |
| 6 | −IN B | Inverting input of channel B - isolated from channel A (123 dB isolation); used for second sensor channel or reference buffer. |
| 7 | OUT B | Amplifier B output - independent output path; enables dual-signal processing (e.g., ECG lead I and II simultaneously). |
| 8 | +IN B | Noninverting input of channel B - identical electrical specs to +IN A; supports matched dual-channel instrumentation topologies. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RRIO op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher 10-μA input bias current (vs. 35 nA typ. for LMV932MM/NOPB); 10 MHz GBW; 2.7–5.5 V supply only. | Better suited for higher-speed sensor interfaces but less optimal for ultra-low-IQ battery monitoring. | Select MCP6022-E/SN when bandwidth >2 MHz is required and supply ≥2.7 V is guaranteed. |
| TLV9002IDR | Lower 0.3-pA input bias current; 1-MHz GBW; 1.8–5.5 V supply; 65-μA IQ (vs. 103 μA min for LMV932MM/NOPB). | Superior for high-impedance pH or ion-selective electrode buffers where IB matters more than speed. | Choose TLV9002IDR for femtoampere-level sensor sources; LMV932MM/NOPB remains preferred for balanced speed/power in portable medical. |
Compared with MCP6022-E/SN and TLV9002IDR, LMV932MM/NOPB uniquely balances 1.4-MHz bandwidth, 100-μA IQ, and 1.8-V operation - making it the most suitable dual RRIO op-amp for cost-sensitive, long-life wearable and battery-monitoring designs where supply headroom is constrained.

FAQ
What is the maximum operating temperature range for LMV932MM/NOPB?
The LMV932MM/NOPB is specified for operation from −40°C to +125°C, meeting industrial and extended-temperature requirements for deployment in automotive cabin modules, outdoor medical devices, and factory-floor sensors. This rating is validated per TI's production test flow and applies to the VSSOP-8 (DGK) package variant shipped as LMV932MM/NOPB.
Does LMV932MM/NOPB support true rail-to-rail input with signals below ground?
Yes - the LMV932MM/NOPB features an input common-mode voltage range extending to V− − 0.2 V, allowing valid operation with inputs as low as −0.2 V when referenced to the negative supply (typically GND). This capability enables direct interfacing with biopotential electrodes or bipolar sensor outputs without external level-shifting circuitry.
Can LMV932MM/NOPB drive a 600-Ω load while maintaining rail-to-rail output swing at 1.8 V?
Yes - at 1.8 V supply and 25°C, LMV932MM/NOPB delivers output swing within 80 mV of both rails into a 600-Ω load, as confirmed in Section 6.5 of the SNOS993P datasheet. This performance is maintained across the full −40°C to +125°C range, with worst-case swing degradation to 120 mV at temperature extremes.
What is the typical supply current per channel for LMV932MM/NOPB at 1.8 V?
The typical supply current per channel for LMV932MM/NOPB is 103 μA at 1.8 V and 25°C, with a maximum of 205 μA across temperature and process variation. This ultra-low quiescent current enables multi-year battery life in always-on wearable applications, and is measured under standard conditions with no load and VCM = V+/2.
Is LMV932MM/NOPB pin-compatible with other packages in the LMV932-N family?
LMV932MM/NOPB (VSSOP-8, DGK) shares identical pinout and function with the SOIC-8 (D) variant of LMV932-N, including matching pin assignments for OUT A, −IN A, +IN A, V−, V+, −IN B, OUT B, and +IN B. No PCB redesign is needed when migrating between these two packages, though thermal and layout considerations differ due to package size and RθJA.
