    DIGI POT 6 Click is a compact add-on board used as a digitally controlled potentiometer. This board features the MCP41HV51, 8-bit dual power rails digital potentiometer with SPI serial interface and volatile memory from Microchip. The MCP41HV51 has a wide operating voltage range, analog from 10 to 36V and digital from 2.7 to 5.5V or implemented as dual-rail (±18V). Its 8-bit configuration supports 255 resistors and 256 steps and provides RAB resistance options of 100 kΩ. It also has a Write Latch function, which will inhibit the volatile wiper register from being updated with the received data. This Click board™ is suitable for precision calibration of set point thresholds, adjustable power supplies, adjustable gain amplifiers and offset trimming, and more.

    DIGI POT 6 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    DIGI POT 6 Click as its foundation uses the MCP41HV51, 8-bit dual power rails digital potentiometer with SPI serial interface and volatile memory from Microchip. It has a wide operating voltage range, analog from 10 to 36V and digital from 2.7 to 5.5V or implemented as dual-rail (±18V) for systems requiring wide signal swing or high power-supply voltages. It supports resistor configurations of 255 resistors and 256 steps and high terminal/wiper current, including the ability to sink/source up to 25mA on all terminal pins for driving larger loads.

    The resistor network of the MCP41HV51 has an 8-bit resolution where each resistor network allows Zero-Scale to Full-Scale connections. All these features combined with an extended temperature range make the MCP41HV51 well suited for a broad range of high-voltage and high-temperature applications, including those in the industrial, automotive, and audio markets.

    DIGI POT 6 click communicates with MCU using the SPI serial interface with a maximum frequency of 10MHz and supports the two most common SPI modes, 0 and 3. This Click board™ also has three terminals labeled as P0A, P0B, and P0W, with an internal architecture that comprises various resistances and switches. The resistance between terminals A and B, RAB, commonly called the “end-to-end” resistance, provides RAB resistance options up to 100 kΩ. In contrast, the wiper terminal, P0W, is digitally programmable to access any 2n tap points on the resistor string.

    This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to properly use the SPI communication lines. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
