Pin Functions

PIN FUNCTION DESCRIPTION
NO. NAME
1 REFIN Input Reference (positive) input. Decouple to GND with a 0.1-μF bypass capacitor and a 10-μF storage capacitor.
2 +VA Supply Analog power supply. Decouple with the GND pin.
3 +IN Input Noninverting analog signal input
4 –IN Input Inverting analog signal input. Note that this input has a limited range of ±0.1 V and is typically grounded at the input decoupling capacitor.
5 GND Supply Device ground. Note that this pin is a common ground pin for both the analog power supply (+VA) and digital I/O supply (+VBD).
6 CONVST Input Convert input. CONVST also functions as the CS input in 3-wire interface mode. Refer to the Description and Timing Diagrams sections for more details.
7 SDO Output Serial data output
8 SCLK Input Serial I/O clock input. Data (on the SDO output) are synchronized with this clock.
9 SDI Input Serial data input. The SDI level at the start of a conversion selects the mode of operation (such as CS or daisy-chain mode). SDI also serves as the CS input in 4-wire interface mode. Refer to the Description and Timing Diagrams sections for more details.
10 +VBD Supply Digital I/O power supply. Decouple with the GND pin.
