LOW-POWER, HIGH-FIDELITY, INTEGRATED CODEC
©2011 INTEGRATED DEVICE TECHNOLOGY, INC.
The ADC digital filters contain a software-selectable digital high pass filter. When the high-pass filter is enabled, the dc
offset is continuously calculated and subtracted from the input signal. The HPOR bit enables the last calculated DC off-
set value to be stored when the high-pass filter is disabled; this value will then continue to be subtracted from the input
signal. To provide support for calibration, the stored and subtracted value will not change unless the high-pass filter is
enabled even if the DC value is changed. The high pass filter may be enabled separately for each of the left and right
channels.
The output data format can be programmed by the system. This allows stereo or mono recording streams at both
inputs. Software can change the polarity of the output signal.
