Product Summary

The PCM3501E is a low cost, 16-bit CODEC designed for modem Analog Front End (AFE) and speech processing applications. The PCM3500’s low power operation from +2.7V to +3.6V power supplies, along with an integrated power-down mode, make it ideal for portable applications. The applications of the PCM3501E are (1)software modems for: Personal Digital Assistant;Notebook and Hand-Held PCs; Set-Top Box; Digital Television; Embedded Systems; (2)portable voice recorder/player; (3)speech recognition/synthesis; (4)teleconferencing products.
