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
