Overview

The LMV324AIPWR is a low-voltage, quad-channel general purpose operational amplifier designed for cost-sensitive applications requiring rail-to-rail output swing. Operating from a minimum supply of 2.5V, it features a very low input bias current of 10 pA and a modest power consumption of 70 uA per channel, making it suitable for battery-powered systems.

Why Choose This Part

The LMV324AIPWR offers a balanced combination of 1.7V/us slew rate and 1 MHz gain bandwidth while maintaining a low 1 mV input offset voltage. Its CMOS architecture provides extremely low input bias current, which minimizes errors when used with high-impedance feedback networks.

Applications

Sensor Signal Conditioning
High impedance input stages for buffering sensors with low output drive capabilities.
Active Filtering
Implementation of low-pass, high-pass, or band-pass filters in portable consumer electronics.
Current Sensing
Low-side current monitoring in power management circuits using its rail-to-rail output capability.
Battery-Powered Instrumentation
General amplification tasks in handheld devices where power efficiency and low voltage operation are critical.

Getting Started

To evaluate this part, use a TSSOP-14 to DIP adapter for breadboard prototyping or integrate it directly into a PCB layout with proper decoupling capacitors (typically 0.1uF) placed close to the V+ pin. Ensure the load does not exceed the 40 mA output current limit per channel to maintain rail-to-rail performance.
