Tempo Semiconductor TSCS25 Stereo CODECs

Tempo Semiconductor TSCS25 Stereo CODECs are low-power, high-fidelity integrated audio ICs with 32-bit stereo playback and stereo record functionality and integrated true cap-less headphone amplifier. The digital audio data interface (I2S, LJ, RJ, TDM) supports both primary and secondary modes for the delivery of linear PCM without the need for an MCLK. BLUETOOTH® PCM data is also supported. Tempo Semiconductor TSCS25 Stereo CODEC offers an enriched audio presence through the built-in audio output processing DSP engine (AOP). The AOP supports 12 bands of stereo parametric EQ, psychoacoustic bass, high-frequency restoration for compressed audio content, 3D stereo enhancement, and broadband DRC, to support multiband compressor, limiter, and expander capabilities.
