ON Semiconductor CAT5116LI-G Digital Potentiometer

The CAT5116LI-G is a high-performance digital potentiometer designed and manufactured by ON Semiconductor, a leading provider of semiconductor-based solutions. This device is part of ON Semiconductor's extensive portfolio of digital potentiometers that offer designers a digitally-controlled resistance option for a wide range of applications.

Featuring a single potentiometer configuration, the CAT5116LI-G provides a total resistance of 100 kOhms with an end-to-end temperature coefficient of 35 ppm/°C, ensuring reliable and stable performance across a wide temperature range. The device operates from a 2.5V to 6V power supply, making it suitable for both 3V and 5V systems. This voltage flexibility allows the CAT5116LI-G to be used in various applications, from battery-operated devices to industrial control systems.

The CAT5116LI-G offers 64 wiper tap points, which can be adjusted via an industry-standard 2-wire I2C-compatible serial interface. This allows for precise and easy adjustment of the resistance value without the need for mechanical potentiometer adjustments, thus providing a more reliable and longer-lasting solution. The non-volatile memory feature ensures that the last wiper position is retained even after the device is powered down, which is crucial for applications that require a specific resistance setting upon power-up.

Designed with built-in wiper resistance of 70 Ohms typical at mid-scale, the CAT5116LI-G ensures low inherent variability and a smooth transition between tap points. Its compact SOT-23-8 package makes it an ideal choice for space-constrained applications such as portable electronics, where size and power efficiency are critical considerations.

Overall, the CAT5116LI-G digital potentiometer from ON Semiconductor is a versatile component that combines digital precision with analog control, offering designers a robust and convenient solution for adjusting resistance values in their electronic designs. With its ease of use, non-volatile memory, and compatibility with serial communication interfaces, the CAT5116LI-G is an excellent choice for a broad array of applications, including automated device calibration, adjustable power supplies, and audio control systems.
