AD5252BRUZ100

AD5252BRUZ100 Description

The AD5252BRUZ100 from Analog Devices Inc. is a dual-channel, 256-tap, non-volatile digital potentiometer with a 100kΩ resistance. Designed for precision control, it operates over a 2.7V to 5.5V single-supply or ±2.25V to ±2.75V dual-supply range, making it versatile for various analog signal conditioning tasks. The device features an I2C interface with selectable addressing, enabling easy integration into multi-device systems. With a ±20% tolerance and a 650ppm/°C temperature coefficient, it ensures stable performance across industrial temperature ranges. Housed in a 14-TSSOP package, it is ideal for space-constrained applications.
