TM FEATURES DESCRIPTION в—Џ COMPLETE STEREO DAC: Includes Digital
Filter and Output Amp The PCM1744 is a complete low cost stereo audio
digital-to-analog converter (DAC), operating off of a
256fS or 384fS system clock. The DAC contains a 3rdorder ∆Σ modulator, a digital interpolation filter, and
an analog output amplifier. The PCM1744 accepts
24-bit input data in a I2S format. в—Џ DYNAMIC RANGE: 95dB
в—Џ MULTIPLE SAMPLING FREQUENCIES:
Up to 96kHz
в—Џ 8x OVERSAMPLING DIGITAL FILTER
в—Џ SYSTEM CLOCK: 256fS / 384fS
в—Џ 24-BIT I2S DATA INPUT FORMAT
в—Џ SMALL 14-PIN SOIC PACKAGE The digital filter performs an 8x interpolation function
and includes de-emphasis at 44.1kHz. The PCM1744
can accept digital audio sampling frequencies from
16kHz to 96kHz, always at 8X oversampling.
