Cough cough, it was me
In fact I had plans on making a test system based on the 6655 and a cpu as external sensor just like ph's. I was about to order a bunch of this chips to make some for other friends interested, but if there's the possibility of a pro grade pcb, we can wait for them
pHaestus: Looking at several parts of the datashet can bring an answer.
First:
Code:
Four Voltage Channels
+12V, +5V, +3.3V, +2.5V
Three External Monitors
One Internal Supply Monitor
Then says about the external monitors:
Code:
ABSOLUTE MAXIMUM RATINGS
VIN1 to GND............................................................-0.3V to +16V
VIN2 to GND..............................................................-0.3V to +6V
VIN3 to GND..............................................................-0.3V to +6V
so it can measure a wide range, but at what accuracy?
Code:
ADC Total Error
VIN1, VIN2, VIN3 between 30% and 120% of nominal ±1 ±1.5 %
Then if you use the 2.5V sensor, Vcore will be well inside typ. +/- 1% error margin.
