The CAT5112VI-10-G is part of a family of digital potentiometers from ON Semiconductor. Digital potentiometers are a type of data acquisition device used to measure changes in resistance that can occur over time, with the intention of controlling a physical system or an electrical signal.

Digital potentiometers are used in a variety of applications, including calibration, linearity correction, feedback control, and signal conditioning. Specifically, the CAT5112VI-10-G is designed for use as a backup to potentiometer-based systems and eliminates the need for manual adjustment or substitution of a specific value.

The CAT5112VI-10-G is a 10-bit digital potentiometer with a resistance range of 0 - 1023 Ohms, operated over an operating voltage of 1.8 - 5.5 V. It has an adjustable wiper and can be adjusted with an on-board control pin or via a digital interface. The wiper code is programmable via the Digital Wiper-Resistor (DWR) interface, with the resistor code also stored in non-volatile memory.

The CAT5112VI-10-G\'s operating temperature range is -40°C to +85°C, with a maximum operating current of 1mA and a maximum supply current of 550uA. The digital potentiometer also features a write time of 1 ms and the ability to activate a push button via a logic control.

The CAT5112VI-10-G is designed to operate in either a single-pole operation mode or a dual-wiper operation mode. In single-pole operation mode, the wiper output is connected to the voltage input, and the resistance is controlled by the logic level applied to the control pin. In dual-wiper operation mode, the wiper output is connected to either side of the resistor, allowing for a variable resistance between the two wiper outputs. This allows for a finer grade of control over the resistance of the device.

The CAT5112VI-10-G is a versatile component that can be used in a variety of situations where more precise control of resistance is required. It is ideal for calibration and linearity correction, as well as feedback control and signal conditioning. The CAT5112VI-10-G is a cost-effective device with a small form factor, making it easy to integrate into a wide variety of applications.
