Replacement verdict
Compatible functional replacement candidate
The AD5262BRUZ20-RL7 and AD5263BRU20 share the same dual-channel 256-position digital potentiometer architecture, 20 kΩ end-to-end resistance, TSSOP-16 footprint, and I²C-compatible serial interface, making them strong functional replacement candidates. Designers should validate the SPI versus I²C control interface difference and confirm the target board's digital supply and logic-level requirements before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5262BRUZ20-RL7 | AD5263BRU20 | Why it matters |
|---|---|---|---|
| Number of Resistor Channels | 2 | 4 | Determines how many independent programmable resistance paths are available in the circuit. |
| Nominal Resistance | 20 kΩ | 20 kΩ | Sets the base end-to-end resistance value used for signal level and current budgeting. |
| Resolution | 8-bit (256 positions) | 8-bit (256 positions) | Defines the number of programmable wiper steps and thus the adjustment granularity. |
| Interface Type | SPI | SPI | Determines the digital communication protocol required to control the device. |
| 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 supply rails for proper operation and signal swing. |
| Package Type | 16-lead TSSOP | 20-lead TSSOP | Affects PCB footprint, pin count, and mechanical compatibility for drop-in replacement. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Specifies the ambient temperature range over which device performance is guaranteed. |
| Pin Count | 16 | 20 | Determines board layout compatibility and whether the parts can share the same footprint. |

Frequently asked questions
What are the main differences between the AD5262BRUZ20-RL7 and the AD5263BRU20?
The AD5262BRUZ20-RL7 is a dual-channel, 256-position digital potentiometer, while the AD5263BRU20 is a quad-channel, 256-position digital potentiometer. Both offer a 20 kΩ end-to-end resistance and are available in a 16-lead TSSOP package, but the AD5263 provides four independent channels versus two on the AD5262.
Are the AD5262BRUZ20-RL7 and AD5263BRU20 pin-compatible?
No. The AD5262 is a 16-lead TSSOP device with two channels, while the AD5263 is a 24-lead TSSOP device with four channels. The different package sizes and pin counts prevent direct pin-to-pin compatibility.
What is the end-to-end resistance of the AD5262BRUZ20-RL7 and the AD5263BRU20?
Both the AD5262BRUZ20-RL7 and the AD5263BRU20 have a nominal end-to-end resistance of 20 kΩ, as indicated by the "20" suffix in their part numbers.
What digital interface do the AD5262BRUZ20-RL7 and AD5263BRU20 use?
Both devices use a 3-wire SPI-compatible serial interface for programming the wiper positions. The AD5263 also includes an additional serial data output (SDO) pin for daisy-chaining multiple devices.
What is the resolution of the AD5262BRUZ20-RL7 and the AD5263BRU20?
Both the AD5262BRUZ20-RL7 and the AD5263BRU20 are 256-position digital potentiometers, providing 8-bit resolution for wiper adjustment.
Can the AD5262BRUZ20-RL7 be used as a drop-in replacement for the AD5263BRU20?
No. The AD5262 has only two channels and a 16-lead package, while the AD5263 has four channels and a 24-lead package. A drop-in replacement is not possible without redesigning the PCB and addressing the additional channels.
What are the operating voltage ranges for the AD5262BRUZ20-RL7 and the AD5263BRU20?
Both devices operate from a single supply of 2.7 V to 5.5 V, or from dual supplies of ±2.7 V to ±5.5 V, allowing use in both unipolar and bipolar signal applications.
Do the AD5262BRUZ20-RL7 and AD5263BRU20 have nonvolatile memory?
No. Both the AD5262BRUZ20-RL7 and the AD5263BRU20 are volatile digital potentiometers. The wiper settings are not retained after power is removed and must be reprogrammed on power-up.
