MC33201/2/4, NCV33202/4, 12V Low Noise, Rail-to-Rail I/O, High Output Drive, Operational Amplifiers, ON Semiconductor?The ON Semiconductor MC33201/2/4, NCV33202/4 Op Amps provide rail-to-rail operation on both the input and output. Drive inputs as high as 200 mV beyond the supply rails without phase reversal on the outputs, and the output can swing within 50 mV of each rail. This rail-to-rail operation enables you to make full use of the supply voltage range availabl
