AD7999YRJZ-1500RL7

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

AD7999YRJZ-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 serial bus clock; an external pull-up resistor is required.
2 SDA bidirectional Digital I/O serial bus bidirectional data line with an open-drain output; an external pull-up resistor is required.
3 VIN0 input Analog input channel 1, single-ended, with an input range of 0 V to VREF.
4 VIN1 input Analog input channel 2, single-ended, with an input range of 0 V to VREF.
5 VIN2 input Analog input channel 3, single-ended, with an input range of 0 V to VREF.
6 VIN3/VREF input Analog input channel 4, single-ended, with an input range of 0 V to VREF; it can also be used to input an external VREF signal.
7 GND power_in Analog ground and the ground reference point for all circuitry; all analog input signals should be referred to this AGND voltage.
8 VDD power_in Power supply input with a range of 2.7 V to 5.5 V.
