EL2228CYZ

Instrumentation, Op Amps, Buffer Amps Overview

The EL2228CYZ is a dual low-noise voltage feedback operational amplifier manufactured by Renesas Electronics, formerly Elantec. It features a gain bandwidth product of 40 MHz and a -3dB bandwidth of 80 MHz at unity gain. The device operates with a supply voltage range of 5V to 24V and draws 5mA of supply current for both channels. Key electrical parameters include a slew rate of 65V/µs, input bias current of 4.5µA, and input offset voltage of 200µV. It is housed in an 8-SOIC package and supports operating temperatures from -40°C to 85°C.
