AD8403ARUZ10-REEL from Analog Devices, in a TSSOP-24. 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 | AGND2 | power_in | Analog Ground 2; all AGND pins must be connected to DGND. |
| 2 | B2 | passive | Terminal B of RDAC 2. |
| 3 | A2 | passive | Terminal A of RDAC 2. |
| 4 | W2 | passive | Wiper of RDAC 2, address 01 (binary). |
| 5 | AGND4 | power_in | Analog Ground 4; all AGND pins must be connected to DGND. |
| 6 | B4 | passive | Terminal B of RDAC 4. |
| 7 | A4 | passive | Terminal A of RDAC 4. |
| 8 | W4 | passive | Wiper of RDAC 4, address 11 (binary). |
| 9 | DGND | power_in | Digital Ground; all AGND pins must be connected to DGND. |
| 10 | SHDN | input | Active low input that opens terminal A and shuts down Variable Resistors 1 through 4. |
| 11 | CS | input | Chip Select Input, Active Low; when CS returns high, data in the serial input register is decoded based on the address bits and loaded into the target DAC register. |
| 12 | SDI | input | Serial Data Input. |
| 13 | SDO | output | Serial Data Output; open drain transistor requires a pull-up resistor. |
| 14 | CLK | input | Serial Clock Input, positive edge triggered. |
| 15 | RS | input | Active low reset to midscale that sets RDAC registers to 80H. |
| 16 | VDD | power_in | Positive Power Supply; specified for operation at both 3 V and 5 V. |
| 17 | AGND3 | power_in | Analog Ground 3; all AGND pins must be connected to DGND. |
| 18 | W3 | passive | Wiper of RDAC 3, address 10 (binary). |
| 19 | A3 | passive | Terminal A of RDAC 3. |
| 20 | B3 | passive | Terminal B of RDAC 3. |
| 21 | AGND1 | power_in | Analog Ground 1; all AGND pins must be connected to DGND. |
| 22 | W1 | passive | Wiper of RDAC 1, address 00 (binary). |
| 23 | A1 | passive | Terminal A of RDAC 1. |
| 24 | B1 | passive | Terminal B of RDAC 1. |
