PIN NAME FUNCTION
1 AIN1
Analog Input 1. Negative differential input relative to AIN0 or positive differential input relative to AIN5
(see Table 5). Connect to the cathode of external diode 1 for remote temperature sensing.
2 SHO
Shield Output. Connect to the shields of twisted-pair input cables used for remote temperature measurements
(see Remote Diode Shielding). Leave unconnected for other applications.
3 AIN2
Analog Input 2. Positive differential input relative to AIN3 or positive differential input relative to AIN5
(see Table 5). Connect to the anode of external diode 2 for remote temperature sensing.
4 AIN3
Analog Input 3. Negative differential input relative to AIN2 or positive differential input relative to AIN5
(see Table 5). Connect to the cathode of external diode 2 for remote temperature sensing.
5 AIN4 Analog input 4. Positive differential input relative to AIN5 (see Table 5).
6 GND Ground. Connect to pin 13.
7 SSTRB
Serial Strobe Output. SSTRB goes low at the beginning of an A/D conversion, and it goes high when the
conversion is nished.
8
CS
Active-Low Chip Select. Data will not be clocked into DIN unless CS is low. When CS is high, DOUT is at high
impedance.
9 DOUT Serial Data Output. DOUT transitions on the falling edge of SCLK.
10 DIN Serial Data Input. DIN latches data on the rising edge of SCLK.
11 SCLK Serial Clock Input. Clocks data in and out of the serial interface.
12 V
DD
Positive Supply Voltage. Bypass with a 0.1µF capacitor to GND.
13 GND Ground (star ground)
14 REF
Reference-Buffer Output/ADC Reference Input. Reference voltage for A/D conversion. Bypass to pin13 with a
0.1µF capacitor. Select reference mode by writing to conguration byte (see Table 2).
15 AIN5 Analog Input 5. Negative differential input relative to AIN0–AIN4 (see Table 5).
16 AIN0
Analog Input 0. Positive differential input relative to AIN1 or positive differential input relative to AIN5
(see Table 5). Connect to the anode of external diode 1 for remote temperature sensing.
