Figure 33-1. Analog Comparator Voltage Scaler vs. Scalefac
3. ADC gain stage cannot be used for single conversion
4.
5. ADC gain stage output range is limited to 2.4 V
Problem fix/Workaround
Use external voltage input for the analog comparator if accurate voltage levels are needed
The ADC gain stage will not output correct result for single conversion that is triggered and
started from software or event system.
Problem fix/Workaround
When the gain stage is used, the ADC must be set in free running mode for correct results.
ADC has increased INL error for some operating conditions
Some ADC configurations or operating condition will result in increased INL error.
In signed mode INL is increased to:
– 6LSB for sample rates above 130ksps, and up to 8LSB for 200ksps sample rate.
– 6LSB for reference voltage below 1.1V when VCC is above 3.0V.
– 20LSB for ambient temperature below 0 degree C and reference voltage below 1.3V.
In unsigned mode, the INL error cannot be guaranteed, and this mode should not be used.
Problem fix/Workaround
None, avoid using the ADC in the above configurations in order to prevent increased INL
error. Use the ADC in signed mode also for single ended measurements.
The amplified output of the ADC gain stage will never go above 2.4 V, hence the differential
input will only give correct output when below 2.4 V/gain. For the available gain settings, this
gives a differential input range of:
