FUNCTION
Analog Voltage Input/Temperature Input Channel 0 or Positive Differential Input Relative to AIN1
Analog Voltage Input/Temperature Input Channel 1 or Negative Differential Input Relative to AIN0
Analog Voltage Input/Temperature Input Channel 2 or Positive Differential Input Relative to AIN3
Analog Voltage Input/Temperature Input Channel 3 or Negative Differential Input Relative to AIN2
Analog Voltage Input/Temperature Input Channel 4 or Positive Differential Input Relative to AIN5
Analog Voltage Input/Temperature Input Channel 5 or Negative Differential Input Relative to AIN4
Analog Voltage Input/Temperature Input Channel 6 or Positive Differential Input Relative to AIN7
Analog Voltage Input/Temperature Input Channel 7 or Negative Differential Input Relative to AIN6

REF
Positive Reference Input in External Mode. Bypass REF with a 0.1μF capacitor to GND when in external mode.
When using the internal reference, REF must be left open.

SCLK
Interrupt Output. Push-pull or open drain with selectable polarity. See Table 9 and the
INT Interrupt Output
section.
Serial Data Output. DOUT transitions on the falling edge of SCLK. High impedance when
CS
is at logic high.
Ground
Positive Power Supply. Bypass with a 0.1μF capacitor to GND.
Serial Data Input. DIN data is latched into the serial interface on the rising edge of the 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.
