1 Introduction
The TLV320DAC23 is a high performance stereo DAC with highly integrated analog functionality. 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. The TLV320DAC23 is the ideal choice for portable digital audio player applications
such as MP3 digital audio players.
Integrated analog features consist of stereo line inputs with an analog bypass path and a stereo headphone amplifier
with analog volume control and mute. The headphone amplifier is capable of delivering 30 mW per channel into 32
.
The analog bypass path allows use of the stereo line inputs and the headphone amplifier with analog volume control
while completely bypassing the DAC, thus enabling further design flexibility such as integrated FM tuners.
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. 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. 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.
Low power consumption and flexible power management allow selective shutdown of DAC functions, thus extending
battery life in portable applications. Couple this design solution with the industry’s smallest package, the TI proprietary
MicroStar Junior
using only 25 mm2 of board area, powerful portable stereo audio designs are easily realizable in
a cost effective, space saving total analog solution.
