AD7314 PIN CONFIGURATION 8-Lead MSOP NC 1 8 VDD CE 2 AD7314 7 ID TOP VIEW SCLK 3 6 SDI (Not to Scale) GND 4 5 SDO NC = NO CONNECT PIN FUNCTION DESCRIPTIONS Pin No. Mnemonic Description
1 NC No Connect. 2 CE Chip Enable Input. The device is selected when this input is high. The SCLK input is disabled when this pin is low. 3 SCLK 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 AD7314 and also to clock data into the control register on the part. 4 GND Analog and Digital Ground. 5 SDO Serial Data Output. Logic output. Data is clocked out of the temperature value register at this pin. 6 SDI Serial Data Input. Serial data to be loaded to the parts’s control register is provided on this input. 7 ID Identification. This pin can be used by a master device to identify the AD7314 in an SPI bus system. This pin has an internal pull-down resistor of 1 kW. 8 VDD Positive Supply Voltage, 2.65 V to 5.5 V. –4– REV.
