AD5260BRU200

Digital Potentiometers Overview

The AD5260BRU200 is a single-channel, 8-bit digitally controlled variable resistor (digital potentiometer) manufactured by Analog Devices. It features a nominal end-to-end resistance of 200 kΩ with a low temperature coefficient of 35 ppm/°C and 256 programmable tap positions. The device operates on a single supply voltage ranging from 4.5 V to 16.5 V or a dual supply of ±4.5 V to ±5.5 V. It utilizes a 4-wire SPI-compatible serial interface for data input and includes a power-on mid-scale preset function. The component is housed in a TSSOP-14 surface-mount package and is rated for operation within an industrial temperature range of –40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current guide, as packaging options such as tube or reel may vary. Confirm that the TSSOP-14 package variant matches the design requirements. Ensure compliance with RoHS standards if applicable to the project specifications. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel variable resistor with high voltage tolerance up to 15 V is required. The 200 kΩ value suits applications needing higher impedance levels compared to the 20 kΩ or 50 kΩ variants. Ensure the logic supply voltage (VL) aligns with the controlling microcontroller's I/O levels. Consider the 35 ppm/°C temperature coefficient for precision applications requiring stable resistance over temperature variations.

Digital Potentiometers Part Context

The AD5260BRU200 belongs to the AD5260/AD5262 family of 15 V digital potentiometers. While the AD5262 offers dual independent channels in a TSSOP-16 package, the AD5260 provides a single channel in a TSSOP-14 package. Both share identical electrical characteristics regarding resistance values, interface protocols, and operating voltages, allowing for flexible design choices based on channel count requirements.

Digital Potentiometers Replacement Considerations

Direct functional substitutes within the same family include the AD5260BRU50 (50 kΩ) and AD5260BRU20 (20 kΩ), which share the same package and interface but differ in resistance values. For dual-channel requirements, the AD5262 series serves as a compatible alternative with additional pins.
