YDA139
Mode Selection Function
YDA139 has mode selection function for selecting analog input and digital input. In the digital input mode, DAC output
signal is output in 12 dB(fixed) of gain. In the analog input mode, analog signal that was input to LIN/RIN is output in a
gain in accordance with the setting of GAIN[1:0] terminal. In the mixing mode, the digital input and analog input is mixed
and output.

Power-down Function
When PDN terminal is L, the power-down mode is selected in YDA139. The mode stops all the circuit functions and
minimizes power consumption. At this time, the output stage of the digital amplifier is disabled (WL*1). In addition, the
High Speed Recovery function allows recovery to the normal operation at 0.8msectPDRwhen setting PDN to H in the
power-down state.
Note)*1: “WL” means output disabled (weak pull-down output).
The relation between power down recovery time (tPDR) and CIN is as follows.
