Texas Instruments LMV358IDGKRG4

Overview

LMV358IDGKRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier. It features rail-to-rail output swing, ground-sensing input common-mode range, and operates across –40°C to 125°C - enabling use in portable media players, HVAC sensor conditioning, and motor control feedback loops.

For engineers reviewing the LMV358IDGKRG4 datasheet, LMV358IDGKRG4 pinout, LMV358IDGKRG4 application, or LMV358IDGKRG4 equivalent, key selection criteria include its VSSOP-8 package footprint, dual-channel rail-to-rail output capability at 2.7 V, input offset voltage ≤7 mV (typ), and compatibility with space-constrained industrial and consumer signal-conditioning designs.

Technical Context

The LMV358IDGKRG4 implements a CMOS input stage with rail-to-rail output stage, supporting true single-supply operation down to 2.7 V while maintaining ≥50 dB CMRR and ≥50 dB PSRR across its full operating temperature range. Its architecture eliminates crossover distortion and enables stable operation with capacitive loads up to 1000 pF when driving 2 kΩ resistive loads.

It operates without external compensation and achieves 60° phase margin with 10 kΩ load and 0–1000 pF capacitive loading. The device does not include shutdown functionality - unlike the LMV324S variant - and shares identical AC/DC performance specifications with the LMV358 family across VSSOP-8, SOIC-8, and TSSOP-8 packages.

FAQ

What is the maximum supply voltage for LMV358IDGKRG4?

The absolute maximum supply voltage for LMV358IDGKRG4 is 5.5 V. Operation beyond this limit risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full specification compliance across that span. At 5 V supply, LMV358IDGKRG4 delivers 1 V/μs slew rate and 1 MHz unity-gain bandwidth while drawing 440 μA total supply current (220 μA per amplifier).

Does LMV358IDGKRG4 support rail-to-rail input?

No, LMV358IDGKRG4 does not support rail-to-rail input - its common-mode input voltage range extends to 0 V (ground) but only up to VCC – 1.2 V at 2.7 V supply (or VCC – 1.0 V at 5 V). However, it does provide true rail-to-rail output swing, delivering signals within 10 mV of both rails into 10 kΩ loads. This makes it ideal for single-supply applications where output dynamic range is critical but input signals remain referenced near ground.

Is LMV358IDGKRG4 pin-compatible with other LMV358 variants?

Yes, LMV358IDGKRG4 is pin-compatible with all standard LMV358 variants in VSSOP-8 (DGK), SOIC-8 (D), and TSSOP-8 (PW) packages. Pin 1 (1OUT) through Pin 8 (2IN+) maintain identical functions and electrical behavior across these packages. No PCB redesign is needed when migrating between DGK, D, or PW footprints - only layout adjustments for thermal and mechanical constraints.

What is the input offset voltage specification for LMV358IDGKRG4?

The input offset voltage for LMV358IDGKRG4 is specified as 7 mV typical and 9 mV maximum at 25°C over the full operating temperature range (–40°C to 125°C). This value remains stable across supply voltages from 2.7 V to 5.5 V. For precision applications requiring lower offset, external trimming or auto-zero architectures (e.g., TLC27L2) should be considered - but LMV358IDGKRG4's 7 mV typ is sufficient for most sensor buffering and general-purpose amplification tasks.

Can LMV358IDGKRG4 drive capacitive loads?

Yes, LMV358IDGKRG4 can reliably drive capacitive loads up to 1000 pF when loaded with a 2 kΩ resistor, maintaining ≥60° phase margin and stable step response. Driving purely capacitive loads (>100 pF) without series resistance may cause peaking or oscillation. For loads exceeding 1000 pF, add a 10–100 Ω isolation resistor in series with the output to preserve stability - confirmed by TI's Figure 7 and Figure 8 in the LMV3xx datasheet (SLOS263W).
