    PCM1690 24-Bit, 192-kHz Sampling, Enhanced Multi-Level ,Eight-Channel Audio Digital-to-Analog Converter

    1 Features 2 Applications1 24-Bit Delta-Sigma DAC Blu-ray DVD Players 8-Channel DAC: HD DVD Players

    AV Receivers High Performance: Differential, fS = 48 kHz Home Theaters THD+N: 94 dB Car Audio External Amplifiers SNR: 113 dB Car Audio AVN Applications Dynamic Range: 113 dB

    Sampling Rate: 8 kHz to 192 kHz3 Description System Clock: 128 fS, 192 fS, 256 fS, 384 fS, The PCM1690 device is a high-performance, single-512 fS, 768 fS, 1152 fS chip, 24-bit, eight-channel, audio digital-to-analog

    Differential Voltage Output: 8 VPP converter (DAC) with differential outputs. The eight-channel, 24-bit DAC employs an enhanced, multi- Analog Lowpass Filter Includedlevel delta-sigma () modulator and supports 8-kHz 4x/8x Oversampling Digital Filter:to 192-kHz sampling rates and a 16-/20-/24-/32-bit

    Passband Ripple: 0.0018 dB width digital audio input word on the audio interface. Stop Band Attenuation: 75 dB The audio interface of the PCM1690 supports the
