The DIGI POT 6 Click Board™ features the Microchip MCP41HVX1 family of devices which have dual power rails (analogue and digital). The analogue power rail allows the high voltage on the resistor network terminal pins. The analogue voltage range is determined by the V+ and V- voltages. The maximum analogue voltage is +36V, while the operating analogue output minimum specifications are specified from either 10V or 20V. As the analogue supply voltage becomes smaller, the analogue 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).
The 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.
