ISL28227FUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28227FUZ is a dual-channel precision operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 10 MHz and a slew rate of 3.6 V/us. The input offset voltage is specified at 70 uV, with an input bias current of 12 nA. Operating from a supply voltage range of 2.25 V to 40 V, the device draws 2.2 mA of operating current. Each channel provides an output current of 45 mA, supported by a common-mode rejection ratio of 120 dB and an input voltage noise density of 2.5 nV/sqrt Hz. It is housed in an MSOP-8 package and operates within a temperature range of -40 C to +125 C.
