AD5293BRUZ-100-RL7

Digital Potentiometers Overview

The AD5293BRUZ-100-RL7 is a single-channel digital potentiometer with 1024 tap positions and 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 uses an SPI-compatible serial interface for wiper setting control and readback. It is housed in a 14-lead TSSOP package and supports an industrial temperature range of −40°C to +105°C.

Digital Potentiometers Feature Summary

• 1024-position resolution with 10-bit code input
• Calibrated ±1% end-to-end resistor tolerance (R-Perf Mode)
• SPI-compatible serial interface with wiper readback capability
• High voltage operation: Single supply 9 V to 33 V; Dual supply ±9 V to ±16.5 V

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable filters, delays, and time constants
• Sensor calibration

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging type and tape/reel specifications. Confirm that the logic supply voltage requirements align with the system design before procurement.

Digital Potentiometers Selection Notes

Select this component when high-voltage digital adjustment is required with precise resistance matching. Ensure the application utilizes the Resistor Performance Mode if strict ±1% tolerance is necessary, as normal mode tolerance is wider. Verify that the SPI clock frequency does not exceed the specified limits.

Digital Potentiometers Part Context

This part belongs to the AD5293 family of single-channel digital potentiometers. It is functionally similar to other variants in the series but distinguished by its 100 kΩ nominal resistance value. Other available resistance options include 20 kΩ and 50 kΩ versions within the same package and feature set.

Digital Potentiometers Replacement Considerations

Direct substitutes include other AD5293 variants with different resistance values, such as AD5293BRUZ-20-RL7 or AD5293BRUZ-50-RL7, provided the circuit impedance requirements are met.
