I want to make a DMM use OM13092 - LPCXpresso board for LPC54608

Since LPC54608 have 12-bit 5 Msps ADC it will be a good choice to build DMM.

Since most IOT device is low power design we measure it's current need use high speed ADC.
When it use at normal measure 12-bit 5Msps can change to 16-bit 312Ksps or 20-bit 19Ksps to add resolution.
