Replacement verdict
Not a drop-in replacement
The AD5260BRUZ50 and AD5262BRU200 are not drop-in replacements for each other. Although both are single-supply digital potentiometers from the same Analog Devices family, they differ fundamentally in channel count, nominal end-to-end resistance, and interface configuration, requiring circuit redesign and firmware adaptation before substitution can be considered.

Key electrical and mechanical differences between the two devices
| Parameter | AD5260BRUZ50 | AD5262BRU200 | Why it matters |
|---|---|---|---|
| Number of Channels | 1 | 2 | Determines how many independent resistance paths can be controlled; a dual-channel part can replace two single-channel devices in space-constrained designs. |
| End-to-End Resistance | 50 kΩ | 200 kΩ | Sets the nominal resistance range and directly affects gain, attenuation, and loading in the target circuit. |
| Number of Positions (Taps) | 256 | 256 | Defines the resolution of resistance adjustment; matching tap count preserves step size and control resolution. |
| Interface Type | SPI | SPI | The digital control protocol must match the host controller to allow direct communication without glue logic. |
| 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) | Compatible supply rails ensure the device operates within the existing power architecture of the system. |
| Package / Mounting | 14-Lead TSSOP, Surface Mount | 16-Lead TSSOP, Surface Mount | Footprint and pin count must match the PCB layout for a drop-in replacement without redesign. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Ensures both parts meet the thermal requirements of the application environment. |
| Resistance Tolerance | ±30% | ±30% | Tolerance affects absolute accuracy of the set resistance and must be accounted for in precision designs. |
| Wiper Current | 1 mA | 1 mA | Maximum wiper current limits the load the digital potentiometer can drive without degradation. |

Frequently asked questions
What are the key differences between the AD5260BRUZ50 and AD5262BRU200?
The AD5260BRUZ50 is a single-channel, 50 kΩ digital potentiometer, while the AD5262BRU200 is a dual-channel, 200 kΩ digital potentiometer. Both are 256-position, I2C-compatible devices from Analog Devices, but they differ in channel count and end-to-end resistance.
Are the AD5260BRUZ50 and AD5262BRU200 pin-compatible?
No. The AD5260BRUZ50 is a single-channel device in a 14-lead TSSOP package, while the AD5262BRU200 is a dual-channel device in a 16-lead TSSOP package. They have different pin counts and pin functions, so they are not drop-in replacements.
What is the resolution of the AD5260BRUZ50 and AD5262BRU200?
Both devices offer 256-position resolution, which corresponds to 8-bit resolution for the digital potentiometer setting.
What supply voltage range do the AD5260BRUZ50 and AD5262BRU200 support?
Both devices operate from a single supply voltage range of 2.7 V to 5.5 V, or a dual supply range of ±2.7 V to ±5.5 V, as specified in the Analog Devices datasheets.
What is the end-to-end resistance tolerance of the AD5260BRUZ50 and AD5262BRU200?
The AD5260BRUZ50 has a nominal end-to-end resistance of 50 kΩ, and the AD5262BRU200 has a nominal end-to-end resistance of 200 kΩ. Both are available with a resistance tolerance of ±30% maximum, as stated in the manufacturer datasheets.
What digital interface do the AD5260BRUZ50 and AD5262BRU200 use?
Both devices use a 2-wire I2C-compatible serial interface, supporting standard and fast I2C modes up to 400 kHz.
Can the AD5260BRUZ50 and AD5262BRU200 be used in daisy-chain configurations?
No. These devices use an I2C interface, which does not support daisy-chaining. Multiple devices can be connected on the same I2C bus using different address pins, but they cannot be cascaded in a shift-register chain.
What are the operating temperature ranges for the AD5260BRUZ50 and AD5262BRU200?
Both devices are specified for the industrial temperature range of −40°C to +85°C, as listed in the Analog Devices datasheets.
