DESCRIPTION
NAME
NO.
ADDR
20
I
I2C slave-address selection pin. See I2C Slave Addressing for more details. This pin
must not be left floating.
AGND
4
G
Analog and digital ground. Connect to PGND, exposed thermal pad, and common
ground plane.
C1–
24
A
Negative pin of charge-pump flying capacitor 1. If charge pump is not used, this pin must
be left floating.
C1+
2
A
Positive pin of charge-pump flying capacitor 1. If charge pump is not used, this pin must
be left floating.
C2–
23
A
Negative pin of charge-pump flying capacitor 2. If charge pump is not used, this pin must
be left floating.
C2+
1
A
Positive pin of charge-pump flying capacitor 2. If charge pump is not used, this pin must
be left floating.
CLK
6
I, OD
Clock input/output. By default this pin is a clock input. If not used, this pin must be
connected to GND or VIN.
