Description
1
SCL
Digital Input. Serial bus clock. External pull-up resistor required.
2
SDA
Digital I/O. Serial bus bidirectional data. Open-drain output. External pull-up resistor required.
3
VIN0
Analog Input 1. Single-ended analog input channel. The input range is 0 V to VREF.
4
VIN1
Analog Input 2. Single-ended analog input channel. The input range is 0 V to VREF.
5
VIN2
Analog Input 3. Single-ended analog input channel. The input range is 0 V to VREF.
6
VIN3/VREF
Analog Input 4. Single-ended analog input channel. The input range is 0 V to VREF. Can also be used to input an
external VREF signal.
7
GND
Analog Ground. Ground reference point for all circuitry on the AD7991/AD7995/AD7999. All analog input signals
should be referred to this AGND voltage.
