Description
Pin to connect a de-coupling capacitor to avoid the output current disturbance,
which is caused by a switching noise such as bias current, of a bias current
setting circuit DAC3.
(Connects a capacitor between BIDCP and BIGND.)
Pin connected to the chip substrate.
Must be used in the same potential as other GND pins.
