Texas Instruments LMV358IDRG4

Overview

LMV358IDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage single-supply operation (2.7 V to 5.5 V), delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in portable media players, HVAC sensor signal conditioning, and netbook power monitoring circuits.

For engineers reviewing the LMV358IDRG4 datasheet, LMV358IDRG4 pinout, LMV358IDRG4 application, or LMV358IDRG4 equivalent, key selection criteria include rail-to-rail output swing down to 60 mV from rail at 10 kΩ load, input offset voltage of 1.7–7 mV, –40°C to 125°C operating temperature range, and SOIC-8 package compatibility with legacy LM358 layouts.

Technical Context

The LMV358IDRG4 integrates two independent voltage-feedback op-amps with complementary-input-stage architecture enabling rail-to-rail output swing and ground-sensing common-mode input range (VICR = –0.2 V to VCC – 0.2 V at 2.7 V). Its 1-MHz unity-gain bandwidth and 60° phase margin ensure stable unity-gain buffer operation with capacitive loads up to 100 pF.

It operates from a single 2.7-V to 5.5-V supply, draws only 210 μA per amplifier (typical), and maintains >50 dB CMRR and PSRR across its full temperature range. No internal shutdown logic is present - unlike LMV324S - making it suitable for always-on analog front-end stages.

Key Specifications

Pinout & Package

LMV358IDRG4 is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm × 1.75 mm, with standard 1.27-mm pitch and gull-wing leads compatible with automated SMT assembly.

FAQ

What is the maximum supply voltage for LMV358IDRG4?

The absolute maximum supply voltage for LMV358IDRG4 is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 2.7 V to 5.5 V, with full specification compliance across that span - including parameters like input offset voltage, CMRR, and output swing. At 5.5 V, output swing remains within 100 mV of each rail under 10-kΩ load.

Does LMV358IDRG4 support dual-supply operation?

Yes, LMV358IDRG4 supports dual-supply operation with ±1.35 V to ±2.75 V total supply (e.g., ±2.5 V). Its input common-mode range extends to –0.2 V, allowing inputs below ground, and output swings rail-to-rail relative to the chosen supplies. However, the device is optimized for single-supply use - most datasheet test conditions and applications assume 2.7–5.5 V single-ended configuration.

Is LMV358IDRG4 pin-compatible with LM358?

Yes, LMV358IDRG4 is pin-compatible with LM358 in SOIC-8 (D) package. Both share identical pinout: OUT A, IN– A, IN+ A, GND, IN+ B, IN– B, OUT B, VCC+. However, LMV358IDRG4 offers rail-to-rail output and ground-sensing input - enhancements not present in LM358 - so direct replacement improves performance without layout changes.

What is the typical input bias current of LMV358IDRG4?

The typical input bias current of LMV358IDRG4 is 11 nA at 25°C and 2.7-V supply, rising to 250 nA maximum over temperature and voltage extremes. This low IIB enables high-impedance sensor interfaces (e.g., pH electrodes or photodiode transimpedance stages) without significant offset error from bias-current-induced voltage drop across feedback networks.

Can LMV358IDRG4 drive capacitive loads?

LMV358IDRG4 can drive capacitive loads up to 100 pF while maintaining ≥60° phase margin and stable unity-gain operation, as verified in datasheet Figure 6 and Figure 7. For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to prevent peaking or oscillation - especially when driving ADC input capacitors or long PCB traces.
