Texas Instruments LMV358IPWR

Overview

LMV358IPWR 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 LMV358IPWR datasheet, LMV358IPWR pinout, LMV358IPWR application, or LMV358IPWR equivalent, key selection considerations include its dual-channel configuration, TSSOP-8 package footprint, rail-to-rail output capability at 2.7 V, low quiescent current, and compatibility with cost-sensitive industrial and consumer signal-conditioning designs.

Technical Context

The LMV358IPWR 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 range. Its input stage includes ESD protection exceeding 2000-V HBM and 1000-V CDM, and it exhibits no crossover distortion due to complementary input pair architecture.

It operates without external compensation over capacitive loads up to 100 pF when driving 2 kΩ, and maintains ≥60° phase margin across temperature (–40°C to 125°C) and supply voltage (2.7 V to 5.5 V). The device lacks shutdown functionality - distinguishing it from the LMV324S variant - and supports both inverting and non-inverting configurations with stable unity-gain performance.

FAQ

What is the maximum capacitive load the LMV358IPWR can drive stably?

The LMV358IPWR maintains ≥60° phase margin and stable unity-gain operation with capacitive loads up to 100 pF when driving a 2-kΩ resistive load, as verified in TI's SLOS263W datasheet Figure 6. For loads >100 pF, external isolation resistor (≥100 Ω) between output and capacitance is recommended to prevent peaking or oscillation - especially critical in ADC driver or filter applications where signal integrity is essential. This behavior is consistent across its full –40°C to +125°C operating range.

Does the LMV358IPWR support true single-supply operation with input signals at ground potential?

Yes, the LMV358IPWR supports true single-supply operation with input common-mode voltage ranging from 0 V (ground) to VCC – 1.35 V at 2.7 V supply, as specified in Section 7.5 VICR parameter. This ground-sensing capability eliminates the need for input biasing networks in applications such as thermistor interfaces, current-sense amplifiers, and single-ended sensor signal conditioning - simplifying design and reducing component count while preserving DC accuracy.

Is the LMV358IPWR pin-compatible with the industry-standard LM358?

No, the LMV358IPWR is not pin-compatible with the LM358. While both are dual op-amps, the LM358 uses an SOIC-8 pinout where Pin 1 is OUT A and Pin 2 is IN– A - same as LMV358IPWR - but LM358's input stage is bipolar and does not support rail-to-rail output or ground-sensing inputs. More critically, LM358 requires minimum 3-V supply and degrades significantly below 5 V, whereas LMV358IPWR is fully specified from 2.7 V. PCB layout reuse is not feasible without schematic and routing changes.

What is the typical input bias current of the LMV358IPWR, and how does it affect high-impedance sensor interfaces?

The LMV358IPWR exhibits 11 nA typical input bias current (IB) at 25°C, with a maximum of 250 nA across temperature - significantly lower than bipolar-input op-amps like LM358 (45 nA typ, but rising sharply with temperature). In high-impedance sensor interfaces (e.g., >100 kΩ source impedance), this low IB minimizes voltage drop and associated offset errors. For example, with a 1-MΩ source, the resulting 250-nA IB introduces only 250 mV of error - well within tolerance for most industrial temperature or pressure sensing applications using the LMV358IPWR.

Can the two amplifiers inside the LMV358IPWR be used independently without crosstalk issues?

Yes, the two amplifiers in the LMV358IPWR operate independently with >90 dB typical crosstalk rejection at 1 kHz (per datasheet Figure 26), ensuring minimal signal coupling between channels. This makes the device suitable for dual-path applications such as stereo audio preamplification or simultaneous voltage/current sensing in power supplies. Layout best practices - including separate ground returns and localized decoupling - further suppress any residual inter-channel interference, preserving channel isolation in precision measurement systems.
