XE3005 / XE3006
Low-Power Audio CODEC
General Description
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.
The XE3006 also includes the Sandman
function, which signals whether a relevant voice or
audio signal is present for the ADC or DAC.
