AD5200BRM50-REEL7

Overview

The AD5200BRM50-REEL7 is a single-channel, 8-bit digital potentiometer from Analog Devices. It features a nominal end-to-end resistance of 50 kΩ with a temperature coefficient of 500 ppm/°C and a tolerance of ±30%. The device offers 256 tap positions controlled via a 3-wire SPI-compatible serial interface. It operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies up to ±2.7 V. Key electrical characteristics include a shutdown current of 5 µA maximum at 5.5 V, a wiper resistance of 100 Ω typical, and a bandwidth of 100 kHz for the 50 kΩ variant. The unit is housed in a compact MSOP-10 package.

Feature Summary

• Single variable resistor with 256 programmable tap positions
• 50 kΩ nominal resistance with linear taper
• 3-Wire SPI-compatible serial control interface
• Internal power-on midscale preset and hardware shutdown pin

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the reel packaging format and tape specifications. Ensure compatibility with standard SMD/SMT PCB mounting processes. Confirm that the component meets required environmental standards for the intended operating temperature range of -40°C to +85°C.

Selection Notes

Select this model when a single-channel digital potentiometer with 50 kΩ resistance is required. The 8-bit resolution provides 256 distinct steps, suitable for applications needing finer control than the 33-position AD5201. Ensure the system supports the 3-wire SPI interface timing requirements, specifically the clock pulse width and data setup times defined in the datasheet.

Part Context

This component belongs to the AD5200/AD5201 family of 256-position and 33-position digital potentiometers manufactured by Analog Devices. The 'BR' designation indicates the industrial temperature grade (-40°C to +85°C), while 'MZ' specifies the MSOP-10 package. The suffix '-REEL7' denotes the specific reel packaging configuration used for automated assembly.

Replacement Considerations

Direct functional replacements within the same series include the AD5200BRM10 (10 kΩ version) if lower resistance is acceptable. For higher resolution needs, consider the AD5292 series. Verify pinout compatibility and interface signaling levels before substituting with other digital potentiometer families.
