Overview

The LM358DR2G is a dual-channel, general-purpose operational amplifier designed for low-power operation across a wide range of supply voltages from 3V to 32V. This internally compensated device features a true differential input stage and a common-mode range that extends down to the negative supply rail, making it well-suited for single-supply applications. Its low input bias current of 45nA and integrated short-circuit protection provide a robust solution for standard signal conditioning tasks.

Why Choose This Part

This amplifier's primary advantage is its versatility in single-supply systems, as it eliminates the need for external biasing components. The 800uA per channel supply current and integrated ESD clamps on the inputs ensure reliable performance in cost-sensitive designs without compromising ruggedness.

Applications

Transducer Amplifiers
Standard gain blocks for amplifying signals from pressure, temperature, or flow sensors in industrial environments.
DC Gain Blocks
Providing stable amplification in low-speed circuits where high-frequency precision is not required.
Current Shunt Sensing
Used in power management circuits to monitor current by amplifying the voltage drop across a low-resistance shunt.
Active Filters
Implementing low-pass or band-pass filters for signal conditioning prior to ADC stages.
