Analog Devices · Temperature Sensors · SOIC-8

ADT7310TRZ-REEL7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCLK input Serial clock input used to clock data in and out of any ADT7310 register.
2 DOUT output Serial data output; data is clocked out on the SCLK falling edge and is valid on the SCLK rising edge.
3 DIN input Serial data input for loading the control registers; data is clocked into the registers on the rising edge of SCLK.
4 CS input Chip select input; the device is selected when this input is low and disabled when it is high.
5 INT output Overtemperature and undertemperature indicator logic output, open-drain, power-up default active-low comparator interrupt, requires a pull-up resistor typically 10 kΩ.
6 CT output Critical overtemperature indicator logic output, open-drain, power-up default polarity active low, requires a pull-up resistor typically 10 kΩ.
7 GND power_in Analog and digital ground.
8 VDD power_in Positive supply voltage of 2.7 V to 5.5 V; the supply should be decoupled with a 0.1 µF ceramic capacitor to ground.
