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.
