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

Stop-Band Attenuation: –65 dB

On-Chip High-Pass Filter: 0.91 Hz (48 kHz)

Flexible PCM Audio Interface

64-times oversampling and includes

digital

–

Master- or Slave-Mode Selectable

Data Formats: 24-Bit I²S, 24-Bit Left-Justified

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.

•

Power Down and Reset by Halting System Clock

Analog Antialias LPF Included

Sampling Rate: 8 kHz–96 kHz

System Clock: 256 f_S, 384 f_S, 512 f_S

Resolution: 24 Bits

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

package.

Dual Power Supplies:

–

5-V for Analog

3.3-V for Digital
