GENERAL DESCRIPTION

The AD5291/AD5292, members of the Analog Devices, Inc.,

DigiPOT+ family of potentiometers, are single-channel, 256-/

1024-position digital potentiometers¹that combine industry

leading variable resistor performance with nonvolatile memory

(NVM) in a compact package. These devices are capable of

operating across a wide voltage range; supporting both dual

supply operation at 10.5 V to 16.5 V and single supply

operation at +21 V to +33 V, while ensuring less than 1% end-

to-end resistor tolerance (R-tolerance) error and offering

20-time programmable (20-TP) memory.

The AD5291/AD5292 device wiper settings are controllable

through the SPI digital interface. Unlimited adjustments are

allowed before programming the resistance value into the

|20-TP memory. The AD5291/AD5292 do not require any

external voltage supply to facilitate fuse blow and there are

20 opportunities for permanent programming. During 20-TP

activation, a permanent blow fuse command freezes the wiper

position (analogous to placing epoxy on a mechanical trimmer).

The AD5291/AD5292 are available in a compact 14-lead TSSOP

package. The part is guaranteed to operate over the extended

industrial temperature range of −40°C to +105°C.

The guaranteed industry-leading low resistor tolerance error

feature simplifies open-loop applications as well as precision

calibration and tolerance matching applications.

¹The terms digital potentiometer and RDAC are used interchangeably.
