LM2902D

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902D is a quad low-power operational amplifier manufactured by STMicroelectronics, despite the onsemi brand query. It features four independent high-gain amplifiers with internal frequency compensation. Key electrical parameters include a gain-bandwidth product of 1.3 MHz and a slew rate of 400 mV/us. The input offset voltage is 7 mV, with an input bias current of 150 nA. It operates from a single supply of 3 V to 30 V or dual supplies of ±1.5 V to ±15 V. The device draws 1.5 mA of operating current and provides 40 mA output current per channel. It is housed in a SOIC-14 package and functions within a temperature range of -40°C to +125°C.
