AIN6/GPIO6
5
AI, DI, DO
Channel 6; configurable as either an analog input (default) or GPIO.
AIN7/GPIO7
6
AI, DI, DO
Channel 7; configurable as either an analog input (default) or GPIO.
AVDD
7
P
Analog supply voltage. Connect a 1-µF capacitor to GND.
CS
11
DI
Chip-select input pin; active low.
The device takes control of the data bus when CS is low.
The SDO pin goes to Hi-Z when CS is high.
DVDD
10
P
Digital I/O supply voltage. Connect a 1-µF capacitor to GND.
GND
9
P
Ground for power supply, all analog and digital signals are referred to this pin.
REF
8
P
Internal reference buffer output; external reference input. Connect a 1-µF capacitor
to GND.
SCLK
13
DI
Clock input pin for the SPI interface.
SDI
14
DI
Serial data input pin for SPI interface.
SDO
12
DO
Serial data output pin for SPI interface.
Thermal Pad
Pad
P
Exposed thermal pad. Connect to ground.
(1)
AI = analog input, DI = digital input, DO = digital output, P = power supply.
