AD5200BRM10-REEL7

Overview

The AD5200BRM10-REEL7 is a single-channel, 8-bit digital potentiometer from Analog Devices. It provides 256 programmable resistance positions with a nominal end-to-end resistance of 10 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 up to ±2.7 V. It features a 3-wire SPI-compatible serial interface for control and includes an internal power-on midscale preset. The unit is housed in a compact 10-pin MSOP package and is rated for operation within the extended industrial temperature range of –40°C to +85°C.

Feature Summary

• 256-position resolution with 10 kΩ nominal resistance
• 3-Wire SPI-compatible serial data input interface
• Single supply (2.7V–5.5V) or dual supply (±2.7V) operation
• Internal power-on midscale preset and shutdown mode

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 the specific ordering suffix against official documentation to confirm packaging details such as reel quantity. Ensure the component meets required RoHS compliance standards for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times prior to procurement planning.

Selection Notes

Select this model when a single variable resistor with 256 discrete steps is required. The 10 kΩ value suits applications needing moderate impedance levels. Consider the ±30% tolerance if absolute resistance accuracy is critical without calibration. The 3-wire interface requires compatible clock and data lines. Verify that the system voltage falls within the 2.7 V to 5.5 V operating range.

Part Context

This component belongs to the AD5200/AD5201 family of digital potentiometers manufactured by Analog Devices. The AD5200 variant specifically offers 256 positions, whereas the AD5201 offers 33 positions. Both share similar electrical characteristics and interfaces but differ in resolution and data word length. The BRM designation indicates the commercial temperature grade and MSOP package type.

Replacement Considerations

Direct pin-compatible replacements include other AD5200 variants with different resistance values (e.g., AD5200BRM50 for 50 kΩ). For higher resolution requirements, consider the AD5292 series. Ensure any substitute maintains the same 3-wire SPI protocol and voltage supply constraints.
