The voltage on the select input determines the address of
the device as shown in table 1.
Table 1. Address codes
Data bits D0 to D3 select the right-channel attenuation in 5
dB steps as shown in table 2. Similarly, bits D8 to D11
select the left-channel attenuation in 5 dB steps.
Table 2. Right-channel 5 dB steps
Data bits D7 selects loudness control. When D7 is 1, loud-
ness control is ON, and when 0, loudness control is OFF.
Audio Signal
The right-channel audio input signal is input on R5dBIN(5
dB attenuation steps). The output, R5dBout, is fed back to
R1dBIN (1 dB attenuation steps). The right-channel audio
output is on R1dBOUT. The left-channel audio signal flow
is identical.
