Description

The TLV320DAC23GQE belongs to TLV320DAC23 family which is a high performance stereo DAC with highly integrated analog functionality. The TLV320DAC23 features an internal oscillator which, when connected to a 12-MHz external crystal, will provide a system clock to the DSP and other peripherals at either 12 MHz or 6 MHz using an internal clock buffer and selectable divider. The DACs within the TLV320DAC23 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. Audio sample rates of 48 kHz and CD standard rates of 44.1 kHz are directly supported from a 12-MHz master clock with 250 fs and 272 fs over-sample rates. The TLV320DAC23 is the ideal choice for portable digital audio player applications such as MP3 digital audio players. While the TLV320DAC23 supports the industry standard over-sample rates of 256 fs and 384 fs, unique over-sample rates of 250 fs and 272 fs are provided which optimize interface considerations in designs using TI C54x DSPs and USB data interfaces. A single 12-MHz crystal can be used to supply clocking to the DSP, USB, and DAC.
