TDFN Pin Description PIN NAME FUNCTION
1 GND Ground 2 DXN Combined Current Sink and ADC Negative Input for Remote Diode. DXN is normally biased to a diode voltage above ground. 3 DXP Combined Current Source and ADC Positive Input for Remote Diode. Place a 2200pF capacitor between DXP and DXN for noise filtering. 4 VCC Supply Voltage Input. Bypass with a 0.1µF to GND. 5 SCK SPI Clock Input 6 CS Chip-Select Input. Pulling CS low initiates an idle state, but the SPI interface is still enabled. A rising-edge of CS initiates the next conversion. 7 SDO SPI Data Output 8 N.C. No Connect. Internally not connected. Can be connected to GND for improved thermal conductivity. — EP Exposed Pad. Internally connected to GND. Connect to a large ground plane to maximize thermal performance. Not intended as an electrical connection point. www.maximintegrated.com Maxim Integrated │ 5
