The LM2904DR2G from onsemi is a dual general-purpose operational amplifier integrating two independent high-gain amplifier channels. It uses a bipolar architecture and supports 3V to 32V single-supply operation, as well as split-supply configurations, making it suitable for sensor conditioning, active filtering, voltage monitoring and general analog-control circuits.
A key advantage of the LM2904 is its common-mode input range extending to the negative supply rail or ground. The output-voltage range also extends toward the negative supply, making the device particularly useful in single-supply systems handling ground-referenced analog signals. The amplifiers are internally frequency compensated and use a true differential input stage.
The LM2904DR2G provides a typical 1MHz gain-bandwidth product and 0.6V/µs slew rate, with approximately 40mA typical output-current capability. Maximum input offset voltage is 7mV, while typical quiescent current is approximately 0.75mA for the device.
Additional features include short-circuit-protected outputs, low input bias current and ESD clamps on the inputs for improved robustness. onsemi identifies the LM2904DR2G as a dual-channel bipolar operational amplifier intended for low-power general-purpose analog applications.
The specific LM2904DR2G ordering option is supplied in an 8-pin SOIC package, case outline 751-07, and is rated for operation from -40°C to +105°C. It is supplied in 2500-piece reel packaging, carries an MSL Level 1 rating at 260°C, and is currently listed by onsemi as Active.
