PIN
NAME
FUNCTION
1
AIN0
Analog Voltage Input/Temperature Input Channel 0 or Positive Differential Input Relative to AIN1
2
AIN1
Analog Voltage Input/Temperature Input Channel 1 or Negative Differential Input Relative to AIN0
3
AIN2
Analog Voltage Input/Temperature Input Channel 2 or Positive Differential Input Relative to AIN3
4
AIN3
Analog Voltage Input/Temperature Input Channel 3 or Negative Differential Input Relative to AIN2
5
AIN4
Analog Voltage Input/Temperature Input Channel 4 or Positive Differential Input Relative to AIN5
6
AIN5
Analog Voltage Input/Temperature Input Channel 5 or Negative Differential Input Relative to AIN4
7
AIN6
Analog Voltage Input/Temperature Input Channel 6 or Positive Differential Input Relative to AIN7
8
AIN7
Analog Voltage Input/Temperature Input Channel 7 or Negative Differential Input Relative to AIN6
9
REF
Positive Reference Input in External Mode. Bypass REF with a 0.1F capacitor to GND when in external mode.
When using the internal reference, REF must be left open.
10
INT
Interrupt Output. Push-pull or open drain with selectable polarity. See Table 9 and the INT Interrupt Output section.
11
DOUT
Serial Data Output. DOUT transitions on the falling edge of SCLK. High impedance when CS is at logic high.
12
GND
Ground
13
VDD
Positive Power Supply. Bypass with a 0.1F capacitor to GND.
14
DIN
Serial Data Input. DIN data is latched into the serial interface on the rising edge of the SCLK.
15
SCLK
Serial Clock Input. Clocks data in and out of the serial interface (duty cycle must be 40% to 60%).
16
CS
Active-Low Chip-Select Input. When CS is low, the serial interface is enabled. When CS is high, DOUT is high
impedance, and the serial interface resets.
