AD5291BRUZ-100

Digital Potentiometers Overview

The AD5291BRUZ-100 is a single-channel digital potentiometer featuring 256-position resolution and a nominal resistance of 100 kΩ. It operates on a single supply from +9 V to +33 V or dual supplies of ±9 V to ±16.5 V, with a logic supply range of 2.7 V to 5.5 V. The device guarantees a maximum ±1% resistor tolerance error in performance mode and includes 20-times programmable (20-TP) nonvolatile memory for wiper settings. It utilizes an SPI-compatible serial interface for control and readback, housed in a compact 14-lead TSSOP package.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm availability and exact specifications. Confirm that the component meets all required environmental and electrical standards for the intended application before finalizing procurement decisions.

Digital Potentiometers Selection Notes

Select this component when high precision is required, as it offers industry-leading low resistor tolerance errors suitable for open-loop applications. Ensure the system supports the specified single or dual supply voltages and that the SPI interface timing aligns with the controller capabilities.

Digital Potentiometers Part Context

This part belongs to the AD5291/AD5292 family of digiPOT+ digital potentiometers. While the AD5292 provides 1024 positions, the AD5291 variant specifically delivers 256 positions. Both share similar features including nonvolatile memory and high-voltage operation capabilities within the same package type.

Digital Potentiometers Replacement Considerations

Direct functional replacements include other single-channel digital potentiometers with comparable resistance values and SPI interfaces. Verify pin compatibility and voltage ratings when substituting with components from different manufacturers.
