**Analog Devices** · Digital Potentiometers · TSSOP-14

AD5260BRUZ50-REEL7 from Analog Devices, in a TSSOP-14. 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 | A | passive | A terminal of the variable resistor (RDAC); the datasheet gives no electrical limit for this pin beyond the Voltage Range VA, B, W of VSS to VDD. |
| 2 | W | passive | Wiper terminal of the variable resistor, tapping the fixed A-to-B resistance at the position set by the digital code. |
| 3 | B | passive | B terminal of the variable resistor; the datasheet gives no electrical limit for this pin beyond the Voltage Range VA, B, W of VSS to VDD. |
| 4 | VDD | power_in | Positive power supply, specified for operation at both 5 V or 15 V, with |VDD| + |VSS| ≤ 15 V. |
| 5 | SHDN | input | Active-low shutdown input that controls the variable resistor and places terminal A in an open circuit. |
| 6 | CLK | input | Serial clock input, positive-edge triggered. |
| 7 | SDI | input | Serial data input. |
| 8 | CS | input | Active-low chip select; when CS returns high, data is loaded into the RDAC register. |
| 9 | PR | input | Active-low preset to midscale that sets the RDAC register to 0x80. |
| 10 | GND | power_in | Ground reference. |
| 11 | VSS | power_in | Negative power supply, specified for operation from 0 V to −5 V. |
| 12 | VL | power_in | Logic supply voltage, which must be the same voltage as the digital logic controlling the AD5260; the VL range is 2.7 V to 5.5 V. |
| 13 | NC | unconnected | No connect; users should not connect anything other than a dummy pad on this pin. |
| 14 | SDO | output | Serial data output, an open-drain transistor that requires a pull-up resistor. |
