Overview

The LMV358AIDR is a dual-channel, general-purpose operational amplifier from Texas Instruments designed for low-voltage operation between 2.5V and 5.5V. It features rail-to-rail output swing and a low quiescent current of 70uA per channel, making it suitable for battery-powered portable electronics. This device includes integrated RFI and EMI filters to minimize sensitivity to high-frequency noise in crowded PCB environments.

Why Choose This Part

The LMV358AIDR offers a gain bandwidth product of 1 MHz and a 1.7V/us slew rate, providing a balance of speed and power efficiency. Its rail-to-rail output maximizes dynamic range on low-voltage rails, while the internal RFI/EMI protection simplifies design in RF-dense applications. The device is unity-gain stable and maintains no-phase reversal during overdrive conditions, ensuring robust signal integrity.

Applications

Sensor Signal Conditioning
Used as a buffer or gain stage for low-impedance sensors in industrial and consumer monitoring systems.
Smoke and Motion Detectors
Provides reliable amplification for PIR or optical sensors while maintaining low standby power consumption.
Active Filtering
Ideal for implementing low-pass or band-pass filters in portable audio or communication devices.
Current Sensing
Utilized in power modules and battery management systems for low-side current monitoring.

Getting Started

For rapid prototyping, mount the 8-SOIC package onto a standard SOIC-to-DIP adapter for use with breadboards. Ensure decoupling capacitors of 0.1uF are placed as close to the V+ pin as possible to maintain stability. Evaluation can be performed using TI generic op-amp evaluation modules or by integrating it into spice simulators like PSpice for TI or LTspice to verify circuit bandwidth and phase margin.
