Description
AD5263BRUZ200 is Analog Devices’ digital potentiometer (DPot) with an I2C interface. It provides an electronically adjustable resistance in a potentiometer network, allowing programmable gain, attenuation, offset trimming, or sensor calibration in analog signal paths. The BRUZ200 suffix specifies the package and industrial temperature variant (compact surface-mount package, suitable for harsh environments). Typical uses include fine-tuning amplifiers, calibrating sensors, or setting reference/divider ratios without mechanical pots. For exact end-to-end resistance, wiper resolution, accuracy, voltage range, and nonvolatile memory options, refer to the AD5263 data sheet and the specific package documentation.
Equivalent
Direct one‑to‑one equivalents for AD5263BRUZ200 do not exist; it is an 8‑bit digital potentiometer. Closest equivalents are other 8‑bit digital pots with the same end‑to‑end resistance and interface. Examples: Microchip MCP41/42 series (10k/50k/100k), TI DS1803 (100k, SPI), Maxim MAX5250/MAX5252 family, Renesas digital pots (various end values). For exact replacement, compare end‑to‑end resistance, terminals A–B–W, interface (I2C/SPI) and package, then cross‑reference.
Features
Here are the typical features for AD5263BRUZ200 (digital potentiometer):
- 8-bit resolution: 256 steps for the wiper position
- SPI-compatible serial interface (SCLK, SI/SDI, CS) for programming
- End-to-end resistance options (orderable variants): 10 kΩ, 50 kΩ, or 100 kΩ
