About the TS4657
The TS4657 is a stereo digital-to analog-converter (DAC) that integrates a high-
performance audio line driver capable of generating a 2.2 Vrms output level from a single
3.0 to 5.5 V supply.
One single supply is sufficient for the digital and analog parts of the circuit, thus eliminating
the need for external regulators.
The TS4657 is a low-power consumption device. It features only 22 mW power dissipation
at a 3.0 V power supply in full operation.
A 16-bit multi-bit sigma delta DAC is used, operating at 256xFs with oversampling digital
interpolation filters. The digital audio data can be 16- to 24-bit long and sample rates from
32 to 48 kHz are supported.
The output stage signal is ground-referenced by using an internal self-generated negative
power supply, and as such external bulky output coupling capacitors are not necessary.
The TS4657 features the following.
