Replacement verdict
Not a drop-in replacement
The AD5260BRUZ20 and AD5262BRU200 are not drop-in replacements for each other. Although both are single-supply digital potentiometers from the same AD526x family, they differ fundamentally in channel count, nominal end-to-end resistance, and interface protocol, which prevents direct substitution without circuit and firmware redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD5260BRUZ20 | 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 | 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 resistance adjustment; identical tap counts give comparable wiper step granularity. |
| Interface Type | SPI | SPI | Determines the digital communication protocol required by the host controller; matching interfaces simplify drop-in replacement. |
| 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) | Must be compatible with the available power rails; identical ranges allow the same supply design to be reused. |
| Wiper Resistance | 60 Ω typical | 60 Ω typical | Adds a fixed series error to the programmed resistance; matching values preserve accuracy in voltage divider and gain-setting applications. |
| Package Type | 14-Lead TSSOP | 16-Lead TSSOP | Affects PCB footprint and pin count; different packages require layout changes and cannot be directly interchanged. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures reliable operation across the intended environmental conditions; identical ranges suit the same application environments. |
| Nonvolatile Memory | No | No | Determines whether the wiper setting is retained after power loss; both volatile parts require reinitialization at startup. |

Frequently asked questions
What are the key differences between the AD5260BRUZ20 and AD5262BRU200?
The AD5260BRUZ20 is a single-channel, 20 kΩ digital potentiometer, while the AD5262BRU200 is a dual-channel, 200 kΩ digital potentiometer. Both are 256-position, SPI-compatible devices from Analog Devices in 14-lead TSSOP packages, but they differ in channel count and end-to-end resistance.
Are the AD5260BRUZ20 and AD5262BRU200 pin-compatible?
No. The AD5260 is a single-channel device and the AD5262 is a dual-channel device, so their pin functions and internal terminal configurations differ. They should not be treated as pin-compatible substitutes without verifying the specific pinout in the respective Analog Devices datasheets.
What is the resolution and number of positions for these digital potentiometers?
Both the AD5260BRUZ20 and AD5262BRU200 are 256-position digital potentiometers, providing 8-bit resolution for wiper adjustment.
What digital interface do the AD5260BRUZ20 and AD5262BRU200 use?
Both devices use a 3-wire SPI-compatible serial interface for programming the wiper position.
What are the end-to-end resistance values and tolerances?
The AD5260BRUZ20 has a 20 kΩ nominal end-to-end resistance, and the AD5262BRU200 has a 200 kΩ nominal end-to-end resistance. Both are available with standard Analog Devices resistance tolerances as specified in their respective datasheets.
Can the AD5260BRUZ20 and AD5262BRU200 operate from the same supply voltage?
Both devices support dual-supply operation and single-supply operation within the ranges specified by Analog Devices. The AD5260 and AD5262 are typically operated from ±2.5 V to ±5.5 V dual supplies or +2.7 V to +5.5 V single supply, but the exact limits should be confirmed in the official datasheets.
What package do the AD5260BRUZ20 and AD5262BRU200 use?
Both the AD5260BRUZ20 and AD5262BRU200 are offered in 14-lead TSSOP packages, denoted by the RU suffix in the part number.
Are the AD5260BRUZ20 and AD5262BRU200 suitable for direct substitution in an existing design?
No. Because they differ in channel count and end-to-end resistance, direct substitution requires validating circuit topology, wiper loading, resistance tolerance, and pinout against the target design and the official Analog Devices datasheets.
