Description
1, 6
REF1, REF2
AI
Reference Input Voltage. The REFx range is 2.4 V to 5.1 V. These pins are referred to the GND pin, and
decouple each pin closely to the GND pin with a 10 µF capacitor.
2, 7
VDD1, VDD2
P
Power Supplies.
3, 8
IN1+, IN2+
AI
Differential Positive Analog Inputs.
4, 9
IN1−, IN2−
AI
Differential Negative Analog Inputs.
5, 10
GND
P
Power Supply Ground.
11, 16
CNV2, CNV1
DI
Conversion Inputs. These inputs have multiple functions. On the leading edge, they initiate conversions
and select the interface mode of the device: chain mode or active low chip select (CS) mode. In CS mode,
the SDOx pins are enabled when the CNVx pins are low. In chain mode, the data must be read when the CNVx
pins are high.
12, 17
SDO2, SDO1
DO
Serial Data Outputs. The conversion result is output on these pins. The conversion result is synchronized
to SCKx.
13, 18
SCK2, SCK1
DI
Serial Data Clock Inputs. When the device is selected, the conversion results are shifted out by these clocks.
14, 19
SDI2, SDI1
DI
Serial Data Inputs. These inputs provide multiple functions. They select the interface mode of the ADC, as
follows: CS mode is selected if the SDIx pins are high during the CNVx rising edge. In this mode, either SDIx
or CNVx can enable the serial output signals when low. If SDIx or CNVx is low when the conversion is
complete, the busy indicator feature is enabled.
15, 20
VIO2, VIO1
P
Input/Output Interface Digital Power. Nominally at the same supply as the host interface (2.5 V or 3.3 V).
1
AI = analog input, DI = digital input, DO = digital output, and P = power.
