AD5172BRMZ10

AD5172BRMZ10 Description

The AD5172BRMZ10 from Analog Devices Inc. is a dual-channel, 10kΩ digital potentiometer with 256-tap resolution, designed for precision analog signal adjustment in embedded systems. It features an I2C interface for digital control, enabling seamless integration with microcontrollers and other digital circuits. Operating within a 2.7V to 5.5V supply range, this device is optimized for low-power applications while maintaining a ±20% resistance tolerance and a low 35ppm/°C temperature coefficient. The One-Time Programmable (OTP) memory ensures stable wiper settings after power cycles, making it ideal for calibration and trimming applications. Housed in a compact 10-MSOP package, it is suitable for space-constrained designs.
