What is the Impact of the COVID-19 Crisis on the Digital Potentiometer IC Market?
The digital potentiometer is a variable resistor controlled by digital signal. The digital potentiometer IC uses digital signals as compared to mechanical movements in normal potentiometer. This is mostly done with the help of resistive ladder, a number of resistors connected in series. This digital resistor is controlled with the help of up and down signals or by protocols such as I²C or SPI. Digital potentiometers are integrated circuits that comes in different variants such as volatile memory and non-volatile memories. The digital potentiometer is a mixed type of signal device. The analog part of the device consists of three terminal component called as potentiometer. The digital part of the potentiometer consists of registers, interface and controls with the potentiometer. Most of the digital potentiometers are controlled by the serial bus. However, some of the potentiometers are designed to be controlled with the help of control logic and front panel switches.
