Description
AD5243BRMZ100-RL7 is a Dual 100 kΩ digital potentiometer from Analog Devices. It provides two rheostat-style wipers whose positions are programmable over a serial interface (I2C-compatible). The device ends-to-end resistance is 100 kΩ, and it operates from a low-voltage supply (typical 2.7–5.5 V). It comes in an 8-pin RoHS-compliant package (BRMZ). Common uses include programmable gain/attenuation, sensor calibration, and offset trimming in analog signal paths. For exact interface protocol, pinout, timing, and electrical details, consult the AD5243 data sheet.
Equivalent
I can provide exact equivalents, but I need specs: end-to-end resistance, number of channels, interface (I2C or SPI), resolution, supply voltage, and package. Do you want cross-references to non-ADI vendors or only Analog Devices replacements? If cross-vendor, I’ll list the closest parts from TI, Microchip, Onsemi, Renesas, etc.
