PCM1808 Audio stereo ADC single-ended analog input decoder amplifier board player module

Product Description

The PCM1808 device is a high-performance, low-cost, single-chip, stereo analog-to-digital converter with single-ended analog voltage input. The PCM1808 device uses a delta-sigma modulator with a 64x oversampling rate and includes a digital decimation filter and a high-pass filter to remove the DC component of the input signal. For a variety of applications, the PCM1808 device supports master and slave modes and two data formats in the serial audio interface. The PCM1808 device supports power-down and reset functions by suspending the system clock. The PCM1808 device is suitable for a variety of cost-sensitive consumer applications that require good performance and operation with a 5V analog supply and a 3.3V digital supply. A highly advanced CMOS process is used in the manufacture of the PCM1808 device. The device is available in a small 14-pin TSSOP package.
