SIGNAL CONDITIONING
The FET switches used for the sample hold on many CMOS
A/D converters release a significant amount of charge injec-
tion which can cause the driving op amp to oscillate. The
amount of charge injection due to the sampling FET switch
on the ISO806 is approximately 5-10% of the amount on
similar ADCs with the charge redistribution DAC (CDAC)
architecture. There is also a resistive front end which attenu-
ates any charge which is released. The end result is a

minimal requirement for the drive capability on the signal
conditioning preceding the A/D. Any op amp sufficient for
the signal in an application will be sufficient to drive the
ISO806.
The resistive front end of the ISO806 also provides a
guaranteed
±
25V overvoltage protection. In most cases, this
eliminates the need for external over voltage protection
circuitry.
