AD5293BRUZ-100

Digital Potentiometers Overview

The AD5293BRUZ-100 is a single-channel, 1024-position digital potentiometer with a nominal resistance of 100 kΩ. It features calibrated ±1% resistor tolerance in Resistor Performance Mode and operates on single supplies from 9 V to 33 V or dual supplies from ±9 V to ±16.5 V. The device utilizes an SPI-compatible serial interface for wiper setting readback and supports daisy-chain operations. It is housed in a compact 14-lead TSSOP package and functions reliably within the extended industrial temperature range of −40°C to +105°C.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm packaging type and tape-and-reel specifications. Ensure that the logic supply voltage requirements are met by the host system before integration.

Digital Potentiometers Selection Notes

Select this component when high-voltage operation and precise resistance matching are required. The 100 kΩ value suits applications needing higher impedance levels compared to the 20 kΩ or 50 kΩ variants. Confirm that the system power supply aligns with the specified single or dual-rail ranges.

Digital Potentiometers Part Context

This part belongs to the AD5293 family of single-channel digital potentiometers. The BRUZ suffix indicates the commercial/industrial temperature grade and the TSSOP-14 surface-mount package configuration.

Digital Potentiometers Replacement Considerations

Other members of the AD5293 family offer different nominal resistances such as 20 kΩ or 50 kΩ. Verify that the selected substitute maintains the required resistance value and voltage ratings for the specific circuit application.
