AD5242BRU10

AD5242BRU10 Description

The AD5242BRU10 is a digital potentiometer from Analog Devices Inc., designed to provide precise control over resistance values in electronic circuits. This device is housed in a 16-lead TSSOP package and offers a resistance range of 10 kΩ with 256 tap positions, ensuring fine-tuned adjustments. The potentiometer operates within a supply voltage range of 2.7V to 5.5V and ±2.3V to ±2.7V, making it suitable for a variety of power supply configurations.

The AD5242BRU10 features a linear taper, which means the resistance changes linearly with the tap position, providing consistent and predictable performance. It supports an I2C interface, enabling easy integration into systems that utilize this communication protocol. The device also includes a selectable address feature, allowing multiple units to be connected to the same bus without address conflicts.
