Note:

1) “-“ means all input conditions.

2) “H” means “H” level, and “L” means “L” level. In addition, “P” means “Pulse oscillation condition”.

3) “*1” means indefinite state.

4) Rch over current detection terminal “OCPLR and OCPHR” can not be operated in Monophonic mode.

5) In the over current detection mode, the mode is continued even if it goes out of the over current condition.

The over current detection mode is canceled by protect reset mode.

detection modes.

7) When YDA136 it-self heats higher than the unusual temperature (Tmax), it will become a high temperature

detection mode.

●Digital Audio Signal Input Mode / Analog Audio Signal Input Mode

YDA136 can input both Digital Audio Signal and Analog Audio Signal.

In case of input for the digital audio signal, be sure to connect DAC output terminal (AOL, AOR) and electron volume

input terminal (AIL, AIR) through capacitor for DC cut.

In addition, in case of input for the analog audio signal; be sure to connect an analog audio signal to electron volume input

terminal (AIL,AIR) through a capacitor for DC cut.

At this time, the output of DAC can be made into High-Z by setting the DAC input format of a control register as MODE8.
