**Analog Devices** · Digital Potentiometers · TSOT-23-8

AD5165BUJZ100-R7 from Analog Devices, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | W | passive | Wiper terminal of the 100 kΩ digital potentiometer. Terminal voltage must satisfy GND ≤ V_W ≤ V_DD. Typical wiper resistance is 50-85 Ω (150 Ω max). |
| 2 | VDD | power_in | Positive power supply, 2.7 V to 5.5 V. Absolute maximum -0.3 V to +7 V referenced to GND. Bypass locally with a decoupling capacitor. |
| 3 | GND | power_in | Digital ground / device common return. |
| 4 | CLK | input | Serial clock input for the 3-wire interface, positive-edge triggered. Maximum clock rate 25 MHz; V_IH ≥ 1.8 V, V_IL ≤ 0.6 V. |
| 5 | SDI | input | Serial data input for the 3-wire interface. The 8-bit wiper code is shifted in MSB first, clocked on the rising edge of CLK. |
| 6 | CS | input | Chip select input, active high (inverted vs. the pin-compatible AD5160). When CS returns low after the shift is complete, the shifted 8-bit code is transferred into the wiper register. |
| 7 | B | passive | B terminal of the 100 kΩ end-to-end resistor. Terminal voltage must satisfy GND ≤ V_B ≤ V_DD; may be biased above or below the A terminal (no polarity restriction). |
| 8 | A | passive | A terminal of the 100 kΩ end-to-end resistor. Terminal voltage must satisfy GND ≤ V_A ≤ V_DD; may be biased above or below the B terminal (no polarity restriction). |
