Digital potentiometers are potentiometers that set resistance based on a digital signal, unlike traditional components of this type, which do it in a mechanical manner. They can also operate as voltage dividers. Usually, they consist of a resistor ladder and CMOS switches for executing logical functions. Other circuits are based on digital-analogue converters. Main advantages of digital potentiometers are their small dimensions, programmable positions, reliability, and lack of interference. Disadvantages include lower accuracy (definite number of positions), lack of fluency, and lower rated voltage. Components of this type are widely used in multimedia, audio and video devices (e.g. amplifiers or mixers). While selecting your potentiometer, pay attention to the number of positions, resolution, and resistance. You can select potentiometers for different mounting (THT or SMD).
Transfer Multisort Elektronik online wholesaler offers digital potentiometers with a wide range of parameters. The search function allows you to select required number of positions (from 32 to 1024), interface (usually I2C or SPI), resistance (from 2.1KΩ to 100KΩ), operating temperature, and resolution. As far as memory is concerned, these components are available with volatile and non-volatile memory (EEPROM). TME catalogue includes components for both THT and SMD mounting. TME offers potentiometers from e.g. Analog Devices, Maxim-Dallas, or Microchip Technology.
