The IC’s preoutput PGAs allow line input signals to be attenuated to match DAC output signal levels. Use the 0dB
setting for maximum performance.
Table 20. Preoutput PGA Registers
The IC includes a single differential receiver amplifier. The receiver amplifier is designed to drive 32I receivers. In
cases where a single transducer is used for the loudspeaker and receiver, use the SPKBYP switch to route the receiver
amplifier output to the left speaker outputs.
