AD5144BRUZ100 General Description
With its resistance range of 100 kilohms and low temperature coefficient of 35 ppm/°C, the AD5144BRUZ100 digital potentiometer is an excellent choice for applications requiring precision and stability. Its quad-channel design and independent potentiometers provide flexibility and control, while the serial interface simplifies integration with microcontrollers and digital systems. The device's low power consumption, both in active mode and shutdown mode, makes it an energy-efficient option for designs where power savings are essential. Moreover, its wiper resistance of 200 ohms and channel-to-channel matching within 0.1% ensure accuracy and reliability in performance. The AD5144BRUZ100 is designed to operate over a wide temperature range, from -40°C to +125°C, and its 16-lead TSSOP package ensures durability and reliability in harsh environments. Additionally, the integration of an internal EEPROM allows for non-volatile memory storage of settings, enhancing its functionality
