Typical Applications
3.9.1
PRECISE COMPARATOR
Some applications require higher DC precision. An
easy way to solve this problem is to use an amplifier
(such as the MCP6041) to gain-up the input signal
before it reaches the comparator. Figure 3-9 shows an
example of this approach.

Precise Inverting
3.9.2
WINDOWED COMPARATOR
Figure 3-10 shows one approach to designing a win-
dowed comparator. The AND gate produces a logic ‘
1
when the input voltage is between V
RB
and V
RT
(where
V
RT
> V
RB
).

3.9.3
BISTABLE MULTI-VIBRATOR
A simple bistable multi-vibrator design is shown in
Figure 3-11. V
REF
needs to be between the power
supplies (V
SS
= GND and V
DD
) to achieve oscillation.
The output duty cycle changes with V
REF
.
