ANALOG INPUT RANGES
The basic connection of the ZN448/9 shown in Fig.15 has an
analogue input range 0 to V
which, in some applications,
may be made available from previous signal conditioning/
scaling circuits. Input voltage ranges greater than this are
accommodated by providing an attenuator on the comparator
input, whilst for smaller input ranges the signal must be
amplified to a suitable level.
Bipolar input ranges are accommodated by off-setting the
analogue input input range so that the comparator always
sees a positive input voltage.
