TS4657IQT 数据手册 ( 数据表 ) - STMicroelectronics

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
