The MC33501/503 operational amplifier provides rail−to−rail operation on both the input and output. The output can swing within 50 mV of each rail. This rail−to−rail operation enables the user to make full use of the entire supply voltage range available. It is designed to work at very low supply voltages (1.0 V and ground), yet can operate with a supply of up to 7.0 V and ground. Output current boosting techniques provide high output current capability while keeping the drain current of the amplifier to a minimum.
