Overview

The LM2904DR is a dual-channel, general-purpose operational amplifier designed to operate from a single power supply over a wide range of voltages from 3V to 26V. This industry-standard component features two independent, high-gain frequency-compensated op-amps with a low supply current of 500uA per channel. It is rated for an extended temperature range of -40C to 125C, making it suitable for industrial and outdoor deployments.

Why Choose This Part

The LM2904DR offers a cost-effective solution for low-power analog applications with a 700 kHz gain bandwidth product and a 0.3V/us slew rate. Its wide operating temperature range and robust 8-SOIC packaging ensure reliability in harsh environments, while the low input bias current of 20 nA minimizes error in high-impedance circuits.

Applications

Transducer Amplifiers
Used to amplify small signals from sensors such as thermocouples or pressure transducers in industrial environments.
DC Gain Blocks
Provides reliable signal amplification in systems where only a single positive power supply rail is available.
Active Filtering
Commonly implemented in low-speed analog signal processing for noise reduction or signal shaping.
Current Sensing
Utilized in power management circuits to monitor current flow across shunt resistors.

Getting Started

To integrate this part, ensure the supply voltage remains within the 3V to 26V range and provide adequate decoupling with a 0.1uF ceramic capacitor near the VCC pin. For prototyping, the 8-SOIC package can be used with a standard SOIC-to-DIP adapter on a breadboard. Simulation models are widely available in SPICE environments for verifying circuit stability and gain characteristics.
