Texas Instruments LMV358IDGK6

Overview

LMV358IDGK6 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 - used in portable media players, HVAC sensor conditioning, and motor control feedback loops.

For engineers reviewing the LMV358IDGK6 datasheet, LMV358IDGK6 pinout, LMV358IDGK6 application, or LMV358IDGK6 equivalent, key selection criteria include its VSSOP-8 package footprint, dual-channel rail-to-rail output capability, low quiescent current at 2.7 V, input offset voltage ≤7 mV, and compatibility with space-constrained industrial and consumer signal-conditioning designs.

Technical Context

The LMV358IDGK6 implements a CMOS input stage enabling rail-to-rail output swing while maintaining input common-mode range extending to ground. Its internal architecture supports stable unity-gain operation with 60° phase margin and 10 dB gain margin under 2 kΩ load conditions.

It operates as a true single-supply op amp: no external level-shifting required for inputs near GND, and outputs swing within 60 mV of VCC+ and 140 mV of GND at 2.7 V with 10 kΩ load - critical for precision analog front-ends in battery-powered systems.

Key Specifications

FAQ

What is the maximum operating temperature range for the LMV358IDGK6?

The LMV358IDGK6 is rated for continuous operation from –40°C to +125°C ambient temperature. This extended industrial temperature range is confirmed in Section 7.3 of the official TI datasheet (SLOS263W), making it suitable for under-hood automotive subsystems, compressor-mounted sensors, and factory-floor controllers where thermal stress exceeds standard commercial-grade limits. The LMV358IDGK6 maintains specified electrical performance across this full range.

Does the LMV358IDGK6 support true rail-to-rail input operation?

No, the LMV358IDGK6 does not support rail-to-rail input - its input common-mode voltage range extends to GND (0 V) but stops at VCC – 1.2 V (not VCC). However, it does provide rail-to-rail *output* swing: output can reach within 60 mV of VCC+ and within 140 mV of GND at 2.7 V supply with 10 kΩ load. This ground-sensing input capability enables direct interfacing with shunt-based current sensors and NTC thermistors referenced to system ground.

Can the LMV358IDGK6 be used with a single 3.3 V supply?

Yes, the LMV358IDGK6 is fully specified and characterized for single-supply operation from 2.7 V to 5.5 V - including 3.3 V. At 3.3 V, it delivers 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and rail-to-rail output swing (within ~80 mV of rails with 10 kΩ load). Its ground-sensing input allows direct connection of 0–3.3 V sensor signals without level-shifting, making LMV358IDGK6 ideal for modern 3.3 V microcontroller-based analog front-ends.

What is the typical supply current consumption of the LMV358IDGK6?

The LMV358IDGK6 draws 210 μA per amplifier (420 μA total for both channels) at 2.7 V and 25°C, as specified in Section 7.5 of the TI datasheet. At 5 V, typical supply current increases to 440 μA per amplifier (880 μA total). This low quiescent current enables use in always-on sensor nodes and battery-powered equipment where multi-year operation is required - significantly lower than legacy alternatives like LM358 (700 μA) or TLV2372 (550 μA).

Is the LMV358IDGK6 pin-compatible with other dual op amps in VSSOP-8 packages?

The LMV358IDGK6 uses the industry-standard VSSOP-8 pinout for dual op amps (1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+), matching TI's TLV2372IDGK, MCP6022-E/MS, and AD8602ARMZ. However, functional compatibility requires verification of bandwidth, input offset, and supply current requirements - e.g., TLV2372IDGK offers higher speed but consumes more current. Always confirm layout and decoupling match the target device's thermal and stability requirements before substitution.
