Replacement verdict
Not a drop-in replacement
The AD5260BRUZ20 and AD5263BRU200 are not drop-in replacements for each other. Although both are single-supply digital potentiometers from Analog Devices, they differ fundamentally in channel count, resistance value, interface protocol, and package footprint, making direct substitution impossible without circuit redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD5260BRUZ20 | AD5263BRU200 | Why it matters |
|---|---|---|---|
| Number of Channels | 1 | 4 | Determines how many independent potentiometer channels are available; a single-channel device cannot directly replace a quad-channel device in multi-channel designs. |
| End-to-End Resistance | 20 kΩ | 200 kΩ | Sets the nominal resistance range and directly affects signal attenuation, current loading, and matching to the surrounding circuit impedance. |
| Number of Positions / Taps | 256 | 256 | Defines the resolution of the digital potentiometer; identical tap counts provide the same adjustment granularity. |
| Interface Type | SPI | I2C | The digital control bus must match the host controller; SPI and I2C are not directly interchangeable without protocol translation. |
| Supply Voltage Range | 4.5 V to 16.5 V (single), ±4.5 V to ±8.25 V (dual) | 4.5 V to 16.5 V (single), ±4.5 V to ±8.25 V (dual) | Determines compatibility with the system power rails; matching ranges allow use in the same supply environment. |
| Nonvolatile Memory | No | No | Indicates whether the wiper setting is retained after power loss; both devices require re-initialization on power-up. |
| Package Type | 14-Lead TSSOP | 14-Lead TSSOP | Footprint and pin count must match for board-level interchangeability; identical packages simplify layout reuse. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device operates reliably within the target application's thermal environment. |
| Wiper Resistance | 60 Ω typical | 60 Ω typical | Adds series resistance in the signal path and affects accuracy, especially at low resistance settings. |

Frequently asked questions
What are the key differences between the AD5260BRUZ20 and AD5263BRU200?
The AD5260BRUZ20 is a single-channel, 20 kΩ digital potentiometer, while the AD5263BRU200 is a quad-channel, 200 kΩ digital potentiometer. The AD5263 integrates four independent potentiometers in one package, whereas the AD5260 provides only one channel. Both are nonvolatile, I2C-compatible digital potentiometers from Analog Devices.
Are the AD5260BRUZ20 and AD5263BRU200 pin-compatible?
No. The AD5260BRUZ20 is offered in a 14-lead TSSOP package, while the AD5263BRU200 is offered in a 24-lead TSSOP package. The pin counts and pin functions differ, so they are not drop-in replacements for each other.
What is the end-to-end resistance of each device?
The AD5260BRUZ20 has a nominal end-to-end resistance of 20 kΩ. The AD5263BRU200 has a nominal end-to-end resistance of 200 kΩ. These values are specified in the respective Analog Devices datasheets.
How many potentiometer channels does each device provide?
The AD5260BRUZ20 provides one single-channel digital potentiometer. The AD5263BRU200 provides four independent digital potentiometer channels in a single IC package.
What digital interface do the AD5260BRUZ20 and AD5263BRU200 use?
Both devices use a 2-wire I2C-compatible serial interface for programming the wiper position. The AD5263 additionally provides address pins that allow multiple devices to be connected on the same I2C bus.
Do these digital potentiometers retain their wiper settings after power-off?
Yes. Both the AD5260BRUZ20 and AD5263BRU200 are nonvolatile digital potentiometers. They store the wiper setting in on-chip EEPROM, so the last programmed position is restored after power is cycled.
What are the typical applications for the AD5260BRUZ20 versus the AD5263BRU200?
The AD5260BRUZ20 is suited for single-channel trim and calibration tasks where board space is limited. The AD5263BRU200 is intended for multi-channel applications such as quad-channel gain and offset adjustment, where four independent 200 kΩ potentiometers are required in one package.
Can the AD5260BRUZ20 and AD5263BRU200 operate from the same supply voltage?
Both devices support single-supply operation from 2.7 V to 5.5 V, as well as dual-supply operation. However, the AD5263BRU200 also supports a wider dual-supply range of ±2.5 V to ±5.5 V. Always verify the exact supply conditions in the respective datasheets before designing.
