Audio Preamplifier Digital Controller IC
Parameters
SPI are:
resistor ladder. Note that each increment of 1 in the
GAIN value results in a 3dB increment in gain. See
Table 4 for gain settings.
Each of the GPO[3:0] bits controls the state of the respective
GPO port as follows:

The 5173 parameters that can be adjusted via
• GAIN (5 bits)
The GAIN[4:0] bits set the gain of the internal
Reset default = 00000 (0dB)
• GPO (4 bits)
