The PCM1808 device is a performance, lowcost, singlechip stereo analogtodigital converter with a singleended analog input. It uses a modulator with 64times oversampling and includes a digital decimation filter and a pass filter that removes the DC component of the input signal. For various applications, the PCM1808 device supports master and slave mode and two data formats in the serial audio interface. The PCM1808 device supports the powerdown and reset functions by halting the system clock. Key features and benefits Singlechip stereo analogtodigital conversion Provides a compact solution with a singleended analog input Reduces board space and BOM compared to multichip implementations Oversampling and filtering 64times oversampling modulator for improved signal quality Digital decimation filter and pass filter to remove DC components Flexible serial interface Supports master and slave modes Supports two data formats in the serial audio interface Power management Powerdown and reset functions achieved by halting the system clock Important attributes Function: performance stereo ADC with integrated oversampling, decimation, and DC removal Compatibility: supports both master and slave operation with two serial data formats for the audio interface Size: singlechip design for compact integration Material: (not specified; presented as a singlechip silicon device) Performance: 64x oversampling with integrated filtering for cleaner digital output Practical use scenarios Use scenario 1: In consumer electronics such as portable audio recorders or compact audio interfaces where a costeffective stereo ADC with simple input is required Use scenario 2: In professional audio equipment such as mixers or installed sound systems that need flexible master/slave operation and multiple serial data formats Use scenario 3: In embedded development projects or evaluation boards where a compact, easytopowerdown stereo ADC is beneficial Notes The description preserves the original device capabilities: singleended input, 64times oversampling, digital decimation filter, pass DC removal, master/slave capability, two serial data formats, and clockbased powerdown/reset.
