Texas Instruments · Digital Potentiometers · SC-70-6

TPL0401B-10DCKR from Texas Instruments, in a SC-70-6. 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 VDD power_in Positive supply voltage input. Recommended operating range 2.7 V to 5.5 V; absolute maximum 7 V.
2 GND power_in Ground reference. The internal L (low) terminal of the potentiometer is tied to this pin.
3 SCL input I2C serial clock input. VIH = 0.7 × VDD; VIL = 0.3 × VDD. Supports Standard mode (100 kHz) and Fast mode (400 kHz). Requires external pull-up.
4 SDA bidirectional I2C serial data line (open-drain). VOL = 0.4 V at IOL = 4 mA. Requires external pull-up to VDD.
5 W passive Wiper terminal of the digital potentiometer. Continuous current rating ±5 mA; recommended wiper current ±2 mA. Wiper resistance ~35 Ω typ.
6 H passive High terminal of the 10 kΩ resistor string. Terminal voltage must remain between GND and VDD; terminal resistance RH ≈ 100 Ω typ.
