These devices perform the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems. They are designed to operate in both synchronous and asynchronous applications and contain an on–chip precision voltage reference. The ML145554 (Mu–Law) and ML145557 (A–Law) are general purpose devices that are offered in 16–pin packages. The ML145564 (Mu–Law) and ML145567 (A–Law), offered in 20–pin packages, add the capability of analog loopback and push–pull power amplifiers with adjustable gain.
