AD5241BRUZ100

AD5241BRUZ100 Description

The AD5241BRUZ100 from Analog Devices Inc. is a 100kΩ, 256-tap digital potentiometer designed for precision analog signal adjustment in embedded systems. Packaged in a 14-pin TSSOP, this single-channel volatile memory potentiometer operates over a 2.7V to 5.5V (±2.3V to 2.7V dual-supply) range, making it suitable for both single and split-rail applications. It features an I²C-compatible interface with selectable addressing, enabling easy integration into multi-device configurations. With a low temperature coefficient of 30ppm/°C and a wiper resistance of 60Ω (typ), it ensures stable performance across varying environmental conditions.
