AS333QW5-7

Overview

The AS333QW5-7 is an automotive-grade, zero-drift CMOS operational amplifier manufactured by Diodes Incorporated. It operates on a single supply from 1.8V to 5.5V or dual supplies of ±0.9V to ±2.5V. The device features rail-to-rail input and output capabilities with common-mode voltage extending 100mV beyond the rails. Key electrical parameters include a typical quiescent current of 17μA, a gain-bandwidth product of 350kHz, and a slew rate of 0.12V/μs. Input offset voltage is typically 8μV with a drift of 0.02μV/°C. It is housed in a SOT25 package.
