AD5272BRMZ-50

Analog Devices · Digital Potentiometers · MSOP-10

AD5272BRMZ-50 from Analog Devices, in a MSOP-10. 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 VDD power_in Positive power supply, 2.7 V to 5.5 V single-supply operation, decoupled with 0.1 µF ceramic and 10 µF capacitors.
2 A passive Terminal A of the RDAC, with VSS ≤ VA ≤ VDD.
3 W passive Wiper terminal of the RDAC, with VSS ≤ VW ≤ VDD.
4 VSS power_in Negative supply, connected to 0 V for single-supply applications, decoupled with 0.1 µF ceramic and 10 µF capacitors.
5 EXT_CAP passive External capacitor pin; connect a 1 µF capacitor between EXT_CAP and VSS with a voltage rating of ≥7 V.
6 GND power_in Ground pin, the logic ground reference.
7 RESET input Active-low hardware reset that refreshes the RDAC register with the 50-TP memory contents; tie to VDD if not used.
8 SDA bidirectional Bidirectional open-drain serial data line that must be pulled to the supply with an external pull-up resistor.
9 SCL input Serial clock line used with SDA to clock data into or out of the 16-bit input registers.
10 ADDR input Tristate address input that sets the two least significant bits (A1, A0) of the 7-bit target address.
