DIGIPOT Click is an accessory board in mikroBUS form factor. It features a single-channel digital potentiometer MCP4161 with 8-bit resolution (256 wiper steps) and industry-standard SPI serial interface.
DIGI POT 4 click is a digitally controlled dual potentiometer, with the resistance of 10KΩ. It has a 10bit resolution which allows for a very smooth linear wiper positioning through 1024 steps. Digital wiper position can be controlled via 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 the power on - just like its mechanical counterpart.
DIGI POT 6 Click features the MCP41HVX1 family of devices which have dual power rails (analog and digital). The analog power rail allows high voltage on the resistor network terminal pins. The analog voltage range is determined by the V+ and V- voltages. The maximum analog voltage is +36V, while the operating analog output minimum specifications are specified from either 10V or 20V. As the analog supply voltage becomes smaller, the analog switch resistances increase, which affects certain performance specifications. The system can be implemented as dual rail (±18V) relative to the digital logic ground (DGND). The device also has a Write Latch (WLAT) function, which will inhibit the volatile wiper register from being updated (latched) with the received data until the Write Latch (WLAT) pin is low. This allows the application to specify a condition where the volatile wiper register is updated (such as zero crossing).
DIGI POT 6 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
DIGI POT 3 click is a versatile and feature-rich digital potentiometer click with 1024 steps and an internal non-volatile memory (EEMEM), which can be used for storing the wiper position, but also for storing various user data. The user EEMEM area has 14 words, each with 16bit length. The Click board™ can be used with both unipolar and bipolar signals, selectable by onboard SMD jumpers. The wiper position can be increased or decreased linearly or by the logarithmic scale (6db/step) with a single command. A special scratch register allows direct programming of the wiper position. It can be stored to the non-volatile memory and on the power on, it is automatically restored. This means that the device restores its last position after the power on - just like its mechanical counterpart.
