ON Semiconductor CAT5112LI-50-G Digital Potentiometer

The CAT5112LI-50-G is a high-quality digital potentiometer designed and manufactured by ON Semiconductor, a leader in the semiconductor industry. This precision device offers a reliable and flexible solution for applications requiring variable resistance settings that can be controlled digitally. It is particularly suitable for adjusting and calibrating system tolerances or controlling signal levels in a variety of electronic circuits.

Featuring a single potentiometer configuration, the CAT5112LI-50-G provides a total resistance of 50kΩ with an impressive 256 resistor taps for fine adjustment. This allows for very precise setting of the resistance value, making it an ideal choice for applications where accuracy is paramount. The digital control interface operates via a simple up/down counter, which is easily interfaced with microcontrollers or other digital logic circuits.

The device operates from a wide power supply range of 2.5V to 6V, ensuring compatibility with both low-voltage and standard logic levels. This versatility makes the CAT5112LI-50-G a suitable option for a broad array of applications, including portable devices, where power efficiency is critical.

Encased in a compact 8-pin PDIP (Plastic Dual In-line Package), the CAT5112LI-50-G is designed for through-hole mounting, which simplifies the integration process into existing designs. The robust packaging also contributes to the durability of the product, allowing it to withstand the rigors of various operating environments.

Key features of the CAT5112LI-50-G include non-volatile memory, which ensures the last resistance setting is retained even when the power is removed, and a wiper resistance as low as 70Ω, which minimizes the impact on the analog signal path. Additionally, the device has an inherent temperature coefficient that helps maintain performance across a wide temperature range.

In summary, the ON Semiconductor CAT5112LI-50-G digital potentiometer delivers precise control, durability, and flexibility, making it an excellent choice for designers looking to add a digitally controlled variable resistor to their electronic projects.
