LA-55: DAC full range is 40A Actual bits is 16 Stable bits is ~21 CT full range is 55 A (FR + 0.5 bits) CT used range is 100 mA (FR - 8.5 bits) ADC resolution over used range is about 8.5 bits Which would give us (FR - 17 bits) -- IF the LA-55 can measure 300uA. This would be 17.5 bits at its full range. Spec is around 1% = 7 bits. CT-0.1: DAC full range is 60A Actual bits is 16 Stable bits is ~21 CT range is 5 mA (FR - 13 bits) ADC resolution over this range is about 8.5 bits Which would give us (FR - 21.5 bits) -- IF the CT-0.1 worked at all.. it's broken. It would be measuring 20uA. This would be 12.2 bits at its full range. Spec is around 1% = 7 bits. A6302: DAC full range is 20A Actual bits is 16 Stable bits is ~21 CT range is 180mA (FR - 6.8 bits) ADC resolution over this range is about 11 bits Which would give us (FR - 17.8 bits) -- Except CT resolution is only about 4 bits at this range. Which gives us 10.8 total, at best.
