Product details
Overview
LMV932MMX from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for 1.8-V operation, delivering 1.4-MHz gain bandwidth, 100-μA per-channel supply current, and output swing within 30 mV of rails under 2-kΩ load. It serves as a precision signal-conditioning front-end in ultra-low-voltage portable systems such as battery-powered health monitors and wearables.
For engineers reviewing the LMV932MMX datasheet, LMV932MMX pinout, LMV932MMX application, or LMV932MMX equivalent, key selection criteria include its 1.8-V minimum supply, −40°C to +125°C operating range, rail-to-rail common-mode input extending 200 mV beyond supplies, and VSSOP-8 packaging suitable for space-constrained PCB layouts.
Technical Context
The LMV932MMX implements a CMOS input stage enabling rail-to-rail input common-mode range (V− −0.2 V to V+ +0.2 V) and low input bias current (15–35 nA), paired with a push-pull output stage supporting rail-to-rail swing into 600-Ω and 2-kΩ loads. Its 1.4-MHz unity-gain bandwidth and 0.35–0.42 V/μs slew rate are stable across 1.8–5.5-V supply operation.
Designed for single-supply use in portable electronics, it features high DC open-loop gain (≥75 dB), 75–100 dB PSRR/CMRR, and 123-dB amplifier-to-amplifier isolation - critical for multi-channel sensing where crosstalk must be minimized in compact layouts.
Key Specifications

Pinout & Package
LMV932MMX is packaged in an 8-pin VSSOP (DGK) with 3.00 mm × 3.00 mm body size and 0.65-mm lead pitch, optimized for automated assembly and thermal performance (RθJA = 184.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (120 μA vs 103 μA), lower GBW (1 MHz), no guaranteed 1.8-V operation - specified only down to 2.7 V. | Less suitable for true 1.8-V systems (e.g., energy-harvesting nodes); requires ≥2.7-V supply for full spec compliance. | Select LMV932MMX when 1.8-V operation, rail-to-rail input beyond rails, or extended temperature range is mandatory. |
| TSV912IDT | Lower input offset (1.5 mV typ), higher GBW (8 MHz), but higher quiescent current (160 μA) and narrower common-mode range (to V+ −0.1 V). | Better for precision DC-coupled apps needing low VOS, but cannot sense signals above supply - unsuitable for high-side current sensing. | Choose LMV932MMX for ultra-low-power, rail-to-rail input flexibility, and wide temperature operation; choose TSV912IDT only if bandwidth and VOS dominate. |
Compared with MCP6022-E/SN and TSV912IDT, LMV932MMX uniquely combines guaranteed 1.8-V operation, input common-mode range extending 200 mV beyond supplies, and 100-μA quiescent current - making it the only option among the three qualified for battery voltage monitoring in single-cell Li-ion systems with sub-2-V brownout conditions.

FAQ
What supply voltage range does the LMV932MMX support?
The LMV932MMX operates from 1.8 V to 5.5 V, with full specifications guaranteed at 1.8 V, 2.7 V, and 5 V. This makes LMV932MMX suitable for direct connection to single-cell Li-ion batteries (2.7–4.2 V) and two-cell alkaline systems (2.4–3.2 V), as well as legacy 3.3-V and 5-V rails. Absolute maximum supply is 6 V.
Does the LMV932MMX support rail-to-rail input and output?
Yes, LMV932MMX provides true rail-to-rail input and output operation. Its input common-mode voltage range extends 200 mV beyond both supply rails (V− −0.2 V to V+ +0.2 V), and its output swings to within 30 mV of each rail under 2-kΩ load - critical for maximizing dynamic range in low-voltage systems.
What is the maximum output current capability of the LMV932MMX?
At 1.8 V supply, LMV932MMX delivers up to 4 mA sourcing and 7 mA sinking short-circuit current. Under normal linear operation into 600-Ω load, it sustains rail-to-rail swing with ≤105 mV headroom. For sustained output currents >10 mA, thermal design and layout must ensure junction temperature remains ≤150°C.
Is the LMV932MMX suitable for high-temperature industrial applications?
Yes, LMV932MMX is fully specified from −40°C to +125°C ambient temperature, with parameters like input offset voltage, supply current, and output swing validated across this range. Its VSSOP-8 package has RθJA = 184.5°C/W, enabling reliable operation in enclosed enclosures or near heat sources when PCB copper area is optimized.
How does the LMV932MMX compare to the single-channel LMV931-N?
LMV932MMX shares identical electrical specifications with LMV931-N per channel - same 1.4-MHz GBW, 100-μA supply current, rail-to-rail I/O, and −40°C to +125°C rating - but integrates two independent amplifiers in VSSOP-8. This reduces board area and BOM count versus two LMV931-N in SC70-5, while maintaining 123-dB channel-to-channel isolation.
