TLV320DAC23RHDR

Product Summary

The TLV320DAC23RHDR is a high performance stereo DAC with highly integrated analog functionality. The DACs within the TLV320DAC23RHDR are comprised of multibit sigma-delta technology with integrated over-sampling digital interpolation filters. Supported data transfer word lengths are 16, 20, 24, and 32 bits with sample rates from 8 kHz to 96 kHz. The DAC sigma-delta modulator features a second order multibit architecture with up to 100 dBA SNR at audio sample rates up to 96 kHz. This enables high quality digital audio playback capability while consuming less than 19 mW during playback only. The TLV320DAC23RHDR is the ideal choice for portable digital audio player applications such as MP3 digital audio players.
