AD5242BRZ100 digital potentiometer 100k Ohm 2 Circuit 256 Taps I²C Interface
The AD5242BRZ100 is a dual-channel, 256-position, I2C-compatible digital potentiometer from Analog Devices that provides precise electronic adjustment functionality equivalent to mechanical potentiometers, trimmers, or variable resistors. Featuring a fixed 100kΩ end-to-end resistance with 1% channel-to-channel matching tolerance, this device utilizes proprietary SiCr thin-film resistor technology to achieve a stable 30ppm/°C temperature coefficient and low-noise operation. Housed in a standard 16-lead SOIC package, it operates from single (+2.7V to +5.5V) or dual (±2.7V) supplies with automatic power-on reset to midscale position, making it ideal for battery-powered applications and systems requiring superior low-temperature-coefficient performance across the extended -40°C to +105°C temperature range.
