RES
Because the sample caps eventually loses charge, clock rates below 10 kHz may affect linearity
performance, especially at elevated temperatures.
These parameters are characterized but not tested in manufacturing.
The t
turned on (AD1CON1<ADON>=’1’). During this time, the ADC result is indeterminate.
Measured accross DAC positive and negative outputs with no load and FORM bit (DACxCON<8>)=φ.
