Description

The TS4657 is a stereo 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.

Features

■ Single 3.0 to 5.5 V supply for DAC and line driver

■ Audio line output: 2.2 Vrms for all VCCrange

■ 16- to 24-bit audio data format stereo DAC, 32 to 48 kHz sample rate

■ I²S, right- or left-justified compatible digital audio interface

■ 95 dB SNR A-weighted at 48 kHz, VCC=5 V

■ 7.4 mA current consumption at VCC=3.0V, full operation

■ Internal negative power supply to ensure ground-referenced, capless outputs

■ No external capacitor needed for the negative power supply generation

■ Integrated structure to suppress pop and click noise

■ Available in thin QFN20 4 mm x 4 mm package

Applications

■ Digital set-top boxes

■ DVD players

■ Digital TVs

■ Notebooks

■ Portable audio equipment

■ Sound cards
