AD7991YRJZ-1500RL7

Analog Devices · Analog To Digital Converters (ADCs) · SOT-23-8

AD7991YRJZ-1500RL7 from Analog Devices, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input Digital input for the serial bus clock; an external pull-up resistor is required.
2 SDA bidirectional Digital I/O serial bus bidirectional data with open-drain output; an external pull-up resistor is required.
3 VIN0 input Analog Input 1, single-ended analog input channel with an input range of 0 V to VREF.
4 VIN1 input Analog Input 2, single-ended analog input channel with an input range of 0 V to VREF.
5 VIN2 input Analog Input 3, single-ended analog input channel with an input range of 0 V to VREF.
6 VIN3/VREF input Analog Input 4, single-ended analog input channel with an input range of 0 V to VREF, which can also be used to input an external VREF signal.
7 GND power_in Analog ground reference point for all circuitry, to which all analog input signals should be referred.
8 VDD power_in Power supply input with a VDD range of 2.7 V to 5.5 V.
