AD5200BRMZ10-REEL7

Overview

The AD5200BRMZ10-REEL7 is a single-channel, 8-bit digital potentiometer with 256 programmable positions. It features a nominal resistance of 10 kΩ and operates on a single supply voltage ranging from 2.7 V to 5.5 V, or dual supplies up to ±2.7 V. The device utilizes a 3-wire SPI-compatible serial interface for data input. Key electrical characteristics include a wiper resistance of 50 Ω (typical), a temperature coefficient of 500 ppm/°C, and a shutdown current of 5 µA maximum. It is housed in a compact 10-pin MSOP package.

Feature Summary

• 256-position resolution controlled via an 8-bit digital code
• 3-Wire SPI-compatible serial interface (CS, CLK, SDI)
• Internal power-on midscale preset function
• Shutdown mode reduces power consumption to microwatt levels

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 ordering suffix REEL7 corresponds to the reel packaging format specified by Analog Devices. Confirm that the BRMZ variant meets the required industrial temperature range of -40°C to +85°C. Ensure the 10 kΩ resistance value aligns with circuit design requirements before procurement.

Selection Notes

Select this component when a single variable resistor with 256 steps is required. The 10 kΩ nominal resistance suits moderate impedance applications. Consider the AD5201 if fewer positions (33) are sufficient, or the AD5241 series if I2C compatibility is preferred over SPI. Verify that the 50 Ω wiper resistance is acceptable for the specific load conditions.

Part Context

This part belongs to the AD5200/AD5201 family of digital potentiometers manufactured by Analog Devices. The 'B' indicates the industrial temperature grade, 'RMZ' denotes the 10-pin MSOP package, and '10' specifies the 10 kΩ nominal resistance. The 'REEL7' suffix identifies the tape and reel packaging configuration.

Replacement Considerations

The AD5200BRMZ10 is the direct equivalent for the same resistance and package. For lower position counts, the AD5201BRMZ10 offers 33 positions. For I2C interfaces, the AD5241 series provides similar functionality with different control protocols.
