Replacement verdict
Not a drop-in replacement
The AD5260BRUZ50 and AD5263BRU200 are not drop-in replacements for each other. The AD5260BRUZ50 is a single-channel 50 kΩ digital potentiometer in a 14-lead TSSOP, while the AD5263BRU200 is a quad-channel 200 kΩ digital potentiometer in a 24-lead TSSOP. They differ in channel count, end-to-end resistance, package footprint, and interface configuration, so a direct substitution is not feasible without circuit redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD5260BRUZ50 | AD5263BRU200 | Why it matters |
|---|---|---|---|
| Number of Channels | 1 | 4 | Determines how many independent resistance paths can be controlled; a 4-channel part cannot be substituted where a single channel is required without redesign. |
| End-to-End Resistance | 50 kΩ | 200 kΩ | Sets the nominal resistance range of the digital potentiometer and directly affects signal attenuation, gain, and current in the target circuit. |
| Interface Type | SPI | I2C | The digital control bus must match the host controller; SPI and I2C are not pin- or protocol-compatible, so substitution requires firmware and wiring changes. |
| Resolution | 8-bit (256 positions) | 8-bit (256 positions) | Determines the number of discrete wiper settings and thus the achievable adjustment granularity of the resistance. |
| 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) | Defines the allowable power rails; both parts share the same range, so supply compatibility is not a differentiator. |
| Package | 14-lead TSSOP | 14-lead TSSOP | Footprint and pin count must match for a drop-in replacement; identical packages simplify board-level substitution. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device meets the thermal requirements of the application; matching ranges mean no derating or qualification differences. |
| Wiper Resistance | ~60 Ω (typical) | ~60 Ω (typical) | Adds a fixed series error to the programmed resistance and affects accuracy in low-resistance settings. |

Frequently asked questions
What are the key differences between the AD5260BRUZ50 and AD5263BRU200?
The AD5260BRUZ50 is a single-channel, 50 kΩ digital potentiometer with 256 positions and an SPI-compatible interface, while the AD5263BRU200 is a quad-channel, 200 kΩ digital potentiometer with 256 positions and an I2C-compatible interface. The AD5260 offers one channel in a 14-lead TSSOP package, whereas the AD5263 provides four independent channels in a 24-lead TSSOP package.
Are the AD5260BRUZ50 and AD5263BRU200 pin-compatible?
No. The AD5260BRUZ50 is housed in a 14-lead TSSOP, and the AD5263BRU200 is housed in a 24-lead TSSOP. They have different pin counts, pin assignments, and package footprints, so they are not pin-compatible or drop-in replacements for each other.
Can the AD5260BRUZ50 and AD5263BRU200 operate from the same supply voltage?
Yes. Both devices are specified for dual-supply operation of ±2.5 V to ±5.5 V or single-supply operation of 2.7 V to 5.5 V, per the Analog Devices datasheets. However, the digital interface logic levels and current consumption may differ, so the system design must be verified against the respective datasheet specifications.
What is the nominal end-to-end resistance of each device?
The AD5260BRUZ50 has a nominal end-to-end resistance of 50 kΩ. The AD5263BRU200 has a nominal end-to-end resistance of 200 kΩ. The "50" and "200" suffixes in the part numbers denote these resistance values.
How many channels does each digital potentiometer provide?
The AD5260BRUZ50 is a single-channel digital potentiometer. The AD5263BRU200 is a quad-channel digital potentiometer, providing four independently programmable resistor channels in one package.
What digital interface does each device use?
The AD5260BRUZ50 uses an SPI-compatible serial interface. The AD5263BRU200 uses an I2C-compatible serial interface. The interface choice affects microcontroller pin count, bus speed, and addressing, so it is a critical selection criterion.
What is the resolution and number of programmable positions for these devices?
Both the AD5260BRUZ50 and AD5263BRU200 provide 256 programmable positions (8-bit resolution) for each channel, as specified in their respective Analog Devices datasheets.
Are the AD5260BRUZ50 and AD5263BRU200 available in the same operating temperature range?
Both devices are specified for the industrial temperature range of −40°C to +85°C, per their Analog Devices datasheets. The "BRUZ" suffix in both part numbers indicates the industrial temperature range and lead-free/RoHS-compliant TSSOP package.
