Dual 20 kΩ digital pot with 256-tap I²C control
The AD5282BRUZ20 is a dual-channel, 256-tap digital potentiometer in a 16-TSSOP package. It is configured as a potentiometer with a linear taper.
I²C interface with selectable address
Communication is over the I²C bus. The selectable address feature lets you assign one of two possible addresses via a logic pin, so two AD5282BRUZ20s can coexist on the same bus. The memory type is volatile.
Package and supply — 16-TSSOP, wide voltage range
The part comes in a 16-TSSOP package (4.40 mm width, 0.173" pitch), surface-mount only. The supply voltage range is 4.5 V to 16.5 V single supply, or ±5 V split supply — so it works with common 5 V logic rails as well as ±5 V analog supplies. The dual supply option allows the wiper to swing below ground in split-supply circuits, which is useful for bipolar signal conditioning.
