AD5200BRMZ50-REEL7

Overview

The AD5200BRMZ50-REEL7 is a single-channel, 8-bit digital potentiometer manufactured by Analog Devices. It provides 256 programmable resistance positions with a nominal end-to-end resistance of 50 kΩ and a tolerance of ±30%. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies of ±2.7 V. It features a 3-wire SPI-compatible serial interface for data input and includes an internal power-on midscale preset. The unit is housed in a compact 10-lead MSOP package and is rated for operation within the extended industrial temperature range of –40°C to +85°C.

Feature Summary

• 256-position resolution controlled via 3-wire SPI serial interface
• Nominal 50 kΩ end-to-end resistance with linear taper
• Internal power-on midscale preset and shutdown mode for low power consumption
• Operates on single (2.7 V to 5.5 V) or dual (±2.7 V) power supplies

Applications

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

Procurement Notes

Verify that the specific ordering suffix '-REEL7' corresponds to the reel packaging format required for the assembly process. Confirm the '50' designation in the part number indicates the 50 kΩ resistance value. Ensure compatibility with the target PCB footprint for the 10-MSOP package. Check for any specific environmental compliance documentation if required by the final product regulations.

Selection Notes

Select this component when a single variable resistor with 256 discrete steps is required. The 50 kΩ resistance value suits applications where moderate current handling is needed without excessive power dissipation. The 3-wire SPI interface minimizes microcontroller pin usage compared to parallel interfaces. Consider the ±30% tolerance if absolute resistance accuracy is critical, as calibration may be necessary.

Part Context

This part belongs to the AD5200/AD5201 family of digital potentiometers. The AD5200 variant specifically offers 8-bit (256-position) resolution, whereas the AD5201 offers 6-bit (33-position) resolution. Both share similar electrical characteristics and pinouts but differ in the number of available tap points and the length of the serial data word required for control.

Replacement Considerations

Direct functional replacements within the same family include the AD5200BRM10 (10 kΩ version). Other Analog Devices digital potentiometers with SPI interfaces may serve as alternatives if pinout and resolution requirements align, though specific electrical parameters like wiper resistance and tolerance should be verified.
