ISL28268FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28268FBZ is a dual-channel, general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail output capability and operates within a supply voltage range of 3 V to 40 V. The device draws 850 µA of supply current for both channels. Key electrical specifications include a maximum input offset voltage of 2600 µV, an input bias current of 230 nA, and a gain-bandwidth product of 4 MHz. The unit supports a slew rate of 1.2 V/µs and delivers an output current of 28 mA per channel. It is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to 125°C.
