This device performs the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems. This device is designed to operate in both synchronous and asynchronous applications and contains an on–chip precision reference voltage. This device has an input operational amplifier whose output is the input to the encoder section.
