Auxiliary Left/Right Clock (Output) - Determines which channel, Left or Right, is currently active
on the Auxiliary serial audio data line.
Auxiliary Serial Clock (Output) - Serial clock for the Auxiliary serial audio interface.
Auxiliary Serial Input (Input) - The 42438 provides an additional serial input for two’s comple-
ment serial audio data.
Differential Analog Output (Output) - The full-scale differential analog output level is specified in
the Analog Characteristics specification table. Each positive leg of the differential outputs may
also be used single-ended.
Quiescent Voltage (Output) - Filter connection for internal quiescent reference voltage.
Differential Analog Input (Input) - Signals are presented differentially to the delta-sigma modula-
tors. The full-scale input level is specified in the Analog Characteristics specification table. Single-
ended inputs may be applied to the positive terminals when the ADCx SINGLE bit is enabled.
Once in Single-Ended Mode, the negative terminal of AIN1-AIN4 must be externally driven to
common mode. See below for a description of AIN5-AIN6 in Single-Ended Mode.
Single-Ended Analog Input (Input) - In Single-Ended Mode, an internal analog mux allows
selection between two channels for both analog inputs AIN5 and AIN6 (see
for details). The unused leg of each input is internally connected to common mode. The full-scale
input level is specified in the Analog Characteristics specification table.
Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling cir-
cuits.
