LM2902BIPWR

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902BIPWR is a quad operational amplifier from the LM2902B series, manufactured by Texas Instruments. It features four high-voltage amplifiers with a supply voltage range of 3V to 36V and an operating temperature range of -40°C to +125°C. The device offers a maximum input offset voltage of ±3mV at 25°C and ±4mV across the full temperature range. Key electrical specifications include a gain-bandwidth product of 1.2 MHz, a slew rate of 0.5 V/µs, and a typical quiescent current of 240µA per amplifier. It utilizes a 14-pin TSSOP package.
