Overview

The LMV321RILT is a single-channel, general-purpose operational amplifier designed for low-voltage operation between 2.7V and 6V. It features rail-to-rail input and output capabilities, making it highly suitable for signal conditioning in systems with limited supply rails. With a typical supply current of 145uA and a gain bandwidth product of 1.3 MHz, it offers a balanced profile for low-power portable electronics.

Why Choose This Part

The LMV321RILT provides a space-efficient solution in a SOT-23-5 package, saving PCB real estate in compact designs. Its rail-to-rail functionality ensures maximum dynamic range for signals even at the minimum 2.7V supply voltage. Additionally, the low input bias current of 16 nA minimizes errors when interfacing with high-impedance signal sources.

Applications

Battery-Powered Instrumentation
Utilized in portable devices where low current consumption is critical for extending battery life.
Active Signal Filtering
Commonly used in low-pass or high-pass active filters for sensor signal processing.
ADC Buffering
Serves as an input buffer for analog-to-digital converters in 3.3V or 5V microcontroller systems.
Current Sensing
Functions as a transimpedance amplifier or differential amplifier for monitoring low-side current shunts.

Getting Started

To evaluate this part, use a standard SOT-23-5 to DIP adapter breadboard for rapid prototyping. Ensure a 0.1uF ceramic bypass capacitor is placed as close to the VCC pin as possible to maintain stability. For automotive applications requiring higher reliability, consider the LMV321RIYLT variant which is AEC-Q100 qualified.
