3. Power Save Function
• When the pin39 is high, the TR Q3 is turned on and Q4 is off, so the bias circuit is enabled. On the other hand, when the
• That is, this function will cause all the circuit blocks of the chip except for OPAMP to be in the off state. thus the low power
• Truth table is as follows;
pin39 is Low (GND) , the TR Q3 is turned off and Q4 is on, so the bias circuit is disabled.
