Mikroelektronika MIKROE-2873 MAX5494 Dual Digital Potentiometer Click Board

Technical description of the product (MIKROE-2873):

MIKROE-2873 DIGI POT 4 Click is a digitally controlled dual potentiometer, with a resistance of 10K. It has a 10-bit resolution which allows for very smooth linear wiper positioning through 1024 steps. Digital wiper position can be controlled via the SPI interface. DIGI POT 4 Click also features a non-volatile durable EEPROM memory for storing the wiper position, which means that the device can restore its last position after power-on – just like its mechanical counterpart. It can be used for digital volume control or precise gain and offset adjustment. It can also be used as LCD digital contrast control, and generally – whenever a precise dual digital potentiometer is required. On-board modules include MAX5494, a 10-bit dual, non-volatile, linear taper, digital potentiometer, from Maxim Integrated. Key Features include accurate positioning of the wiper, via the 1024 different steps, non-volatile EEPROM memory used for recalling the wiper positions after power-on, very good bandwidth and low THD on input signals. The interface is SPI and input voltage is 3.3V or 5V. Click board size is M (42.9 x 25.4 mm).
