1 VDD +650 +1079 AI Power Supply. Nominally 2.5 V to 5.5 V. 2 REF +475 +1078 AI Reference Input/Output. 3 REFIN −473 +1078 AI Internal Reference Output/Reference Buffer Input. 4 GND −659 +1079 P Power Supply Ground. 5 GND −838 +1079 P Power Supply Ground. 6 IN4 −1085 +892 AI Analog Input Channel 4. 7 IN5 −1085 +653 AI Analog Input Channel 5. 8 IN6 −1085 −528 AI Analog Input Channel 6. 9 IN7 −1085 −769 AI Analog Input Channel 7. 10 COM −1085 −1015 P Common Channel Input. All input channels, IN[7:0], can be referenced to a common-mode point of 0 V or VREF/2 V. 11 CNV −519 −1087 DI Conversion Input. On the rising edge, CNV initiates the conversion. During conversion, if CNV is held low, the busy indictor is enabled. 12 DIN −71 −1087 DI Data Input. Use this input for writing to the 14-bit configuration register. The configuration register can be written to during and after conversion. 13 SCK +231 −1087 DI Serial Data Clock Input. This input is used to clock out the data on SDO and clock in data on. 14 SDO +667 −1087 DO Serial Data Output. 15 VIO +1079 −1056 P Input/Output Interface Digital Power. Nominal y at the same supply as the host interface (1.8 V, 2.5 V, 3 V, or 5 V). 16 IN0 +1085 −769 AI Analog Input Channel 0. 17 IN1 +1085 −528 AI Analog Input Channel 1. 18 IN2 +1085 +653 AI Analog Input Channel 2. 19 IN3 +1085 +894 AI Analog Input Channel 3. 20 VDD +997 +1079 P Power Supply. Nominal y 2.5 V to 5.5 V. 1 AI is analog input, P is power, DI is digital input, and DO is digital output. Rev.
