PIN FUNCTION DESCRIPTIONS
Pin SOT-23 MSOP
Mnemonic Pin No. Pin No. Description
GND 1 7 Analog and Digital Ground
DIN 2 6 Serial Data Input. Serial data to be loaded to the part’s control register is
provided on this input. Data is clocked into the control register on the rising
edge of SCLK.
V
DD
35 Positive Supply Voltage, 2.7 V to 5.5 V
SCLK 4 4 Serial Clock Input. This is the clock input for the serial port. The serial clock
is used to clock data out of the temperature value register of the AD7814 and
to clock data into the control register on the part.
CS 53 Chip Select Input. Logic input. The device is selected when this input is low.
The SCLK input is disabled when this pin is high.
DOUT 6 2 Serial Data Output. Logic output. Data is clocked out of the temperature
value register at this pin. Data is clocked out on the falling edge of SCLK.
NC 1, 8 No Connect
