Additional Details

The CAT5114VI-50 is typically available in an 8-pin SOIC package. The resistance value is determined by the digital input signals. Since it is a volatile potentiometer, the resistance setting must be re-established each time the power is cycled. Detailed electrical characteristics, including resistance range and linearity, can be found in the manufacturer's datasheet. When implementing this device, it's essential to adhere to the recommended operating conditions and provide appropriate decoupling capacitors to ensure stable operation. The -50 at the end of the part number likely indicates a specific resistance value; consult the datasheet to confirm.
