PCM1807 - 101dB SNR Stereo ADC With Single-Ended Inputs

The PCM1807 is high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1807 uses a delta-sigma modulator with 64-times oversampling and includes a digital decimation filter and high-pass filter that removes the dc component of the input signal. For various applications, the PCM1807 supports master and slave mode and two data formats in serial audio interface.

The PCM1807 has many functions which are con- trolled through SPI serial-control port: power down, fade-in and fade-out, polarity control, etc.

The PCM1807 is suitable for wide variety of cost-sensitive consumer applications where good per- formance and operation with a 5-V analog supply and 3.3-V digital supply is required. The PCM1807 is fabricated using a highly advanced CMOS process and is available in a small, 14-pin TSSOP package.
