TS4657IQT Datasheet PDF - ST Microelectronics

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
