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. |
