Texas Instruments PCM3501 Low Voltage, Low Power, 16-Bit, Mono SoundPlus(TM) Voice/Modem Codec PCM3501E/2KG4

The PCM3501E/2KG4 is a low voltage, low power, 16-bit mono voice and modem codec designed for applications such as software modems, portable voice recorders, and teleconferencing products. It operates with a supply voltage range of +2.7V to +3.6V and features a power-down mode that reduces current consumption to 60 µA (typical). The codec supports sampling frequencies from 7.2 kHz to 26 kHz and provides a dynamic range of 88 dB at an 8 kHz sampling rate. This device integrates a delta-sigma ADC and DAC, along with necessary filters and a synchronous serial interface that allows for easy integration with DSP and RISC processors. It also supports Time Division Multiplexing (TDM), enabling up to four codecs to share a single serial bus. The PCM3501E is packaged in a compact 24-lead SSOP, making it suitable for space-constrained applications. Its operating temperature range is from -25°C to +85°C, ensuring reliability in various environments.
