Stereo PDM-to-I²S or

TDM Conversion IC

ADAU7002

Data Sheet

FEATURES

GENERAL DESCRIPTION

64× decimation of a stereo pulse density modulation (PDM)

bit stream to pulse code modulation (PCM) audio data

Slave I²S or time division multiplexed (TDM) output interface

Configurable TDM slots

I/O supply operation: 1.62 V to 3.6 V

64× output sample rate PDM clock

The ADAU7002 converts a stereo PDM bit stream into a PCM

output. The source for the PDM data can be two microphones

or other PDM sources. The PCM audio data is output on a

serial audio interface port in either I²S or TDM format.

The ADAU7002 is specified over the commercial temperature

range (−40°C to +85°C). It is available in a halide-free, 8-ball,

1.56 mm × 0.76 mm, wafer level chip scale package (WLCSP).

64×/128×/192×/256×/384×/512× output sample rate BCLK

Automatic BCLK ratio detection

Output sample rate: 4 kHz to 96 kHz

Automatic PDM CLK drive at 64× the sample rate

Automatic power down with BCLK removal

0.67 mA operating current at 48 kHz and 1.8 V IOVDD supply

Shutdown current: <1 µA

8-ball, 1.56 mm × 0.76 mm, 0.4 mm pitch WLCSP

Power-on reset

APPLICATIONS

Mobile computing

Portable electronics

Consumer electronics
