Product details
Overview
LMV932MAX 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 105 mV of rails under 600-Ω load - enabling precision signal conditioning in space-constrained, battery-powered health monitors and wearables.
For engineers reviewing the LMV932MAX datasheet, LMV932MAX pinout, LMV932MAX application, or LMV932MAX equivalent, key selection criteria include ultra-low supply voltage support (1.8 V), rail-to-rail I/O with 200-mV beyond-rail common-mode range, −40°C to +125°C operating temperature, and SOIC-8 packaging for industrial-grade portable electronics design.
Technical Context
The LMV932MAX implements a CMOS input stage with rail-to-rail input common-mode range extending 200 mV beyond both supply rails and rail-to-rail output stage capable of driving 600-Ω loads while maintaining stability with up to 1000-pF capacitive loads. Its 101-dB DC open-loop gain ensures high-accuracy low-frequency amplification in sensor front-ends.
Designed for single-supply operation down to 1.8 V, the device achieves 0.35 V/μs slew rate at 1.8 V and maintains phase margin ≥67° across supply voltages (1.8 V to 5.5 V), supporting stable unity-gain buffer and active filter configurations without external compensation.
Key Specifications

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-I/SN | Higher 170-μA supply current; 10-μV typical VOS; no beyond-rail input capability. | Better DC precision but unsuitable for sub-ground sensing; requires ≥2.7-V supply. | Select when ultra-low offset dominates over supply voltage flexibility and rail-to-rail input. |
| TSV912IDT | 1.1-MHz GBW; 155-μA supply current; 1.5-V min supply; no beyond-rail input. | Lower bandwidth and higher power; limited to ≥1.5-V systems with standard CMVR. | Choose only if footprint compatibility with ST's SOIC-8 is required and 1.8-V operation is not mandatory. |

FAQ
What is the minimum supply voltage for reliable operation of LMV932MAX?
The LMV932MAX is fully specified from 1.8 V to 5.5 V, with guaranteed functionality-including rail-to-rail input/output swing and 1.4-MHz gain bandwidth-at 1.8 V. Operation below 1.8 V is not characterized; attempting to power LMV932MAX below 1.8 V may result in degraded CMRR, increased VOS, or failure to meet slew rate specifications.
Does LMV932MAX support true rail-to-rail input with signals below ground?
Yes. LMV932MAX features an input common-mode voltage range from V− − 0.2 V to V+ + 0.2 V. When powered with V− = 0 V (single supply), this allows inputs as low as −0.2 V - enabling direct connection to high-side current-sense shunts or sensors with negative offset without external level-shifting circuitry.
Can LMV932MAX drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes. At 1.8-V supply, LMV932MAX delivers output swing within 105 mV of both rails into a 600-Ω load - meaning a minimum output of 0.077 V and maximum of 1.72 V. This preserves >94% of the 0–1.8 V dynamic range, critical for maximizing resolution in low-voltage ADC interfaces.
What is the thermal resistance (RθJA) of LMV932MAX in its SOIC-8 package?
The LMV932MAX in SOIC-8 (D package) has a junction-to-ambient thermal resistance (RθJA) of 125.9°C/W under standard JEDEC test conditions. This value assumes a 2-layer board with 1-in² copper pour; actual thermal performance improves with enhanced PCB copper area or thermal vias.
Is LMV932MAX suitable for automotive cabin temperature environments?
Yes. LMV932MAX is rated for operation from −40°C to +125°C and is commonly deployed in automotive cabin applications such as seat occupancy sensors and HVAC ambient light controls. Its 125°C max junction temperature and robust ESD rating (±2000 V HBM) ensure reliability in thermally demanding vehicle interiors.
