Function
- Rch Analog Negative Input 1 Pin (When DIE1 bit = “L”, this pin must be open.)
(Note 3)
I Lch Analog Positive Input 2 Pin (DIE2 bit = “H”)
I Lch Analog Input 2 Pin (DIE2 bit = “L”)
- Lch Analog Negative Input 2 Pin (When DIE2 bit = “L”, this pin must be open.)
(Note 3)
I Rch Analog Positive Input 2 Pin (DIE2 bit = “H”)
I Rch Analog Input 2 Pin (DIE2 bit = “L”)
- Rch Analog Negative Input 2 Pin (When DIE2 bit = “L”, this pin must be open.)
(Note 3)
I Lch Analog Positive Input 3 Pin (DIE3 bit = “H”)
I Lch Analog Input 3 Pin (DIE3 bit = “L”)
- Lch Analog Negative Input 3 Pin (When DIE3 bit = “L”, this pin must be open.)
(Note 3)
- Ground Pin, 0V
- Analog Power Supply Pin, 3.0V∼3.6V
I Positive Voltage Reference Input Pin, AVDD1
O Common Voltage Output Pin, AVDD1x1/2
Large external capacitor around 2.2µF is used to reduce power-supply noise.
I Rch Analog Positive Input 3 Pin (DIE3 bit = “H”)
I Rch Analog Input 3 Pin (DIE3 bit = “L”)
- Rch Analog Negative Input 3 Pin (When DIE3 bit = “L”, this pin must be open.)
(Note 3)
Note 1. This pin becomes OVF pin when OVFE bit is set to “1”.
Note 2. This pin becomes DZF pin when OVFE bit is set to “0”.
Note 3. This pin becomes analog negative input pin in differential input mode, and becomes output pin invert the positive
input pin in single-end input mode. This pin must be open in single-end input mode.
Note 4. All digital input pins except for pull-down must not be left floating.
