AD5200BRMZ10

Overview

The AD5200BRMZ10 is a single-channel, 8-bit digital potentiometer with 256 tap positions and a nominal resistance of 10 kΩ. It features a 3-wire SPI-compatible serial interface for data input and volatile memory to retain the wiper setting during power-off. The device operates on a single supply from 2.7 V to 5.5 V or dual supplies of ±2.3 V to ±2.7 V. Key electrical characteristics include a nominal resistor tolerance of ±30%, a temperature coefficient of 500 ppm/°C, and a typical positive supply current of 15 µA. It includes an internal power-on midscale preset and a shutdown pin for low-power operation.

Feature Summary

• 256-position resolution controlled via 3-wire SPI serial interface
• Nominal resistance of 10 kΩ with ±30% tolerance
• Operates on single supply (2.7 V to 5.5 V) or dual supply (±2.3 V to ±2.7 V)
• Volatile latch maintains programmed resistance value

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 the manufacturer's documentation to confirm packaging type and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for the intended market. Ensure the supply voltage range aligns with the system design constraints before procurement.

Selection Notes

Select this component when a 256-step resolution is required for precise resistance control. The 10 kΩ nominal value suits applications requiring moderate current handling. Consider the ±30% tolerance if absolute resistance accuracy is critical without calibration. The volatile memory requires a backup strategy if power loss retention is necessary.

Part Context

This part belongs to the AD5200/AD5201 family of programmable resistor devices. The AD5200 variant specifically provides 256 positions, whereas the AD5201 offers 33 positions. Both share similar interfaces and electrical characteristics but differ in resolution and data word length (8-bit vs. 6-bit).

Replacement Considerations

Direct substitutes within the same family include the AD5200BRM50, which shares the same package and interface but offers a 50 kΩ nominal resistance. Other variants may require verification of pin compatibility and electrical parameter alignment.
