(1)
The leakage current for the Compa terminals is identical to I
lkg(Px.y)
specification.
(2)
The input offset voltage can be cancelled by using the CAEX bit to invert the Compa inputs on successive measurements. The
two successive measurements are then summed together.
(3)
The response time is measured at P2.2/CAOUT/TA0/CA4 with an input voltage step, with Compa already enabled (CAON = 1).
If CAON is set at the same time, a settling time of up to 300 ns is added to the response time.
