3 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

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 PCM1808 device supports master

and slave mode and two data formats in serial audio interface.

The PCM1808 device supports the power-down and

reset functions by means of halting the system clock.

The PCM1808 device is suitable for wide variety of cost-sensitive consumer applications requiring good

performance and operation with a 5-V analog supply

and 3.3-V digital supply. Fabrication of the PCM1808

device uses a highly advanced CMOS process. The device is available in a small, 14-pin TSSOP

package.
