AD5201BRM50-REEL7

Overview

The AD5201BRM50-REEL7 is a single-channel digital potentiometer featuring 33 programmable positions and a nominal end-to-end resistance of 50 kΩ. It operates on a single supply from 2.7 V to 5.5 V or dual supplies of ±2.7 V. The device utilizes a 3-wire SPI-compatible serial interface with 6-bit data resolution. Key electrical characteristics include a wiper resistance of 50 Ω to 100 Ω, a temperature coefficient of 500 ppm/°C, and a shutdown current of less than 5 µA. It includes an internal power-on midscale preset and is housed in a compact MSOP-10 package.

Feature Summary

• 33-position digital control via 6-bit serial input
• 50 kΩ nominal end-to-end resistance
• Single (2.7V–5.5V) or dual (±2.7V) supply operation
• Internal power-on midscale preset function

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Programmable filters and time constants
• Line impedance matching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact resistance value and packaging configuration. Ensure compatibility with the system's serial clock speeds and logic voltage levels before integration.

Selection Notes

Select this component for applications requiring precise digital adjustment of 50 kΩ resistive networks. The 33-position resolution suits moderate precision requirements. Verify that the 500 ppm/°C temperature coefficient meets the thermal stability needs of the circuit design.

Part Context

This part belongs to the AD5200/AD5201 family of programmable resistor devices manufactured by Analog Devices. The AD5201 variant specifically provides 33 positions compared to the 256 positions of the AD5200. The BRM suffix indicates the industrial temperature range and MSOP package type.

Replacement Considerations

Direct functional replacements within the same family include the AD5201BRMZ series for different package options. Cross-family substitutes like the MAX5410 require verification of pinout compatibility and interface timing differences.
