概述
Description
AD5258BRMZ50-R7 is an Analog Devices digital potentiometer (digipot) device. It provides electronically programmable resistance via an I2C interface, enabling adjustable gain/attenuation in analog front-ends (e.g., sensor calibration, audio, signal conditioning). The “50” in the part name indicates a 50 kΩ end-to-end resistance (typical for this family). BRMZ is the RoHS-compliant MSOP-8 package, and “-R7” denotes tape-and-reel packaging. This part is used when you need software-controlled, repeatable resistance settings in a compact, low‑power package. For exact details—number of wipers/channels, wiper resolution, voltage range, and memory behavior—please consult the AD5258 datasheet.
Equivalent
I can help, but I need specs. The AD5258BRMZ50-R7 is an Analog Devices octal digital potentiometer with I2C interface. Please provide:
- end-to-end resistance (Ω)
- number of channels (likely 8)
- supply voltage range
- wiper resolution
- package/temperature requirements
- whether you want a direct cross-reference or a functionally equivalent part
With those, I can suggest concrete equivalents.
- end-to-end resistance (Ω)
- number of channels (likely 8)
- supply voltage range
- wiper resolution
- package/temperature requirements
- whether you want a direct cross-reference or a functionally equivalent part
With those, I can suggest concrete equivalents.
