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.
