AD5258BRMZ1

AD5258BRMZ1 Description

The AD5258BRMZ1 from Analog Devices Inc. is a 1kΩ, 64-tap digital potentiometer designed for precision analog signal adjustment in embedded systems. Housed in a compact 10-MSOP package, it operates over a 2.7V to 5.5V supply range, making it suitable for low-power and portable applications. The device features an I2C interface for digital control, enabling seamless integration with microcontrollers and other digital systems. With a ±30% tolerance and a 200ppm/°C temperature coefficient, it balances cost-effectiveness with stable performance across industrial temperature ranges. Its 75Ω typical wiper resistance ensures minimal signal distortion in voltage-divider or variable-resistor configurations.
