AD5258BRMZ50

AD5258BRMZ50 is an Analog Devices digitally controlled potentiometer (digipot) with an I2C-compatible interface. It provides programmable resistance in analog signal paths—useful for gain control, attenuation, offset trimming, and calibration—under software control. The BRMZ50 suffix denotes the RoHS-compliant MSOP-8 package. Key features typically include low power operation and programmable wiper positions, with optional non-volatile memory to retain settings on power-down (variant dependent). End-to-end resistance and the number of potentiometer sections vary by device; common options span from a few kΩ up to 100 kΩ. Typical applications include programmable gain stages, sensor calibration, and attenuation in audio or instrumentation systems. For exact specifications (RAB, wiper resolution, number of pots, I2C address, voltage range, and memory behavior), refer to the latest AD5258 datasheet.

The AD5258BRMZ50 is an 8-channel I2C digital potentiometer with 50 kΩ end-to-end resistance. There isn’t a single exact cross-reference from other vendors. Closest substitutes are other 8-channel I2C digipots from Analog Devices (same family in other packages) or similar devices from Renesas/TI depending on end-to-end resistance. For a precise substitute, provide your required end-to-end value (10k/50k/100k), supply voltage, and interface (I2C vs SPI).
