XE3005 / XE3006

Low-Power Audio CODEC

GENERAL DESCRIPTION

FEATURES

•

Ultra low-power consumption, below 2 mW

Low-voltage operation down to 1.8 V

Sandman™ function to reduce system power

consumption (XE3006)

The XE3005 is an ultra low-power CODEC (Analog to

Digital and Digital to Analog Converter) for voice and

audio applications. It includes microphone supply,

preamplifier, 16-bit ADC, 16-bit DAC, serial audio

interface, power management and clock management

for the ADC and the DAC. The sampling frequency of

the ADC and of the DAC can be adjusted from 4 kHz to

48 kHz.

•

Single supply voltage

Adjustable sampling frequency: 4 – 48 kHz

Digital format: 16 bit 2s complement

Requires a minimum number of external

components

•

Easy interfacing to various DSPs

Direct connection to microphone and speaker

Various programming options

The XE3006 also includes the Sandman™ function,

which signals whether a relevant voice or audio signal is

present for the ADC or DAC.
