Texas Instruments LMV932IDGKR

Overview

LMV932IDGKR from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for 1.8-V to 5-V single-supply operation, delivering 1.4 MHz gain bandwidth, 100 μA per channel supply current, and output swing within 80 mV of rails into 600 Ω - enabling precision signal conditioning in battery-powered industrial sensors and portable audio front-ends.

For engineers reviewing the LMV932IDGKR datasheet, LMV932IDGKR pinout, LMV932IDGKR application, or LMV932IDGKR equivalent, key selection criteria include its –40°C to 125°C operating range, VSSOP-8 (DGK) package footprint, rail-to-rail common-mode input extending 200 mV beyond rails, and verified performance at 1.8-V supply with <4 mV max input offset voltage.

Technical Context

The LMV932IDGKR integrates two independent amplifiers in a single VSSOP-8 package, each featuring Class AB output stage and input stage biased to support rail-to-rail common-mode voltage (VICR = VCC– – 0.2 V to VCC+ + 0.2 V). Its internal architecture enables stable operation with capacitive loads up to 1000 pF while driving 600 Ω.

It operates across 1.8 V to 5 V supply range with guaranteed specifications at all voltages: 1.4 MHz GBW at 1.8 V, 1.5 MHz at 5 V; CMRR ≥75 dB and PSRR ≥75 dB over full temperature range; and input bias current ≤75 nA at –40°C to 125°C.

FAQ

What is the maximum supply voltage rating for LMV932IDGKR?

The absolute maximum supply voltage (VCC+ – VCC–) for LMV932IDGKR is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 1.8 V to 5 V, with full electrical specifications guaranteed across that span. At 5 V, LMV932IDGKR delivers 1.5 MHz gain bandwidth and 4.855-V high-level output swing into 600 Ω, confirming robustness at upper rail.

Does LMV932IDGKR support true rail-to-rail input common-mode range?

Yes, LMV932IDGKR supports rail-to-rail input with 200 mV beyond-rail capability: VICR extends from VCC– – 0.2 V to VCC+ + 0.2 V. This allows direct interface to signals exceeding supply rails - critical for thermocouple or current-sense amplifier topologies. At 1.8 V supply, it accepts inputs from –0.2 V to 2.0 V, verified across –40°C to 125°C.

What is the typical output drive capability of LMV932IDGKR into 600 Ω?

At 1.8 V supply, LMV932IDGKR delivers output swing within 80 mV of each rail into 600 Ω (i.e., 0.08 V to 1.72 V), with sourcing/sinking short-circuit current of 3.3 mA/5 mA respectively. These values are measured per channel and remain stable across temperature, enabling reliable ADC driver and sensor excitation roles without external buffers.

Is LMV932IDGKR suitable for automotive applications?

Yes, LMV932IDGKR is characterized for operation from –40°C to 125°C and meets automotive ambient requirements for cabin and body-control modules. Its 2.7-V and 5-V specifications, 2000-V HBM ESD rating, and rail-to-rail input make it suitable for HVAC sensor interfaces and infotainment auxiliary amplifiers - though system-level AEC-Q200 validation remains the designer's responsibility.

What package type does LMV932IDGKR use, and what are its key mechanical features?

LMV932IDGKR uses the VSSOP-8 (DGK) package: 2.3 mm × 2.0 mm body, 0.5 mm lead pitch, 0.45 mm nominal thickness, and exposed thermal pad (non-functional). It complies with JEDEC MO-178, has MSL Level 1 rating, and supports fine-pitch SMT assembly - ideal for space-constrained portable and industrial PCBs where SOIC-8 is too large.
