Product Summary
The PCM3500E is a Low Voltage, Low Power, 16-Bit, Mono VOICE/MODEM CODEC. It is designed for modem Analog Front End (AFE) and speech processing applications. The PCM3500E’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 PCM3500E integrates all of the functions needed for a modem or voice CODEC, including delta-sigma digital-to-analog and analog-to-digital converters, input anti-aliasing filter, digital high-pass filter for DC blocking, and an output low-pass filter. Applications of the PCM3500E include (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.
