Typical Applications

4.9.1

PRECISE COMPARATOR

Some applications require higher DC precision. An

easy way to solve this problem is to use an amplifier

(such as the MCP6291) to gain-up the input signal

before it reaches the comparator. Figure 4-12 shows

an example of this approach.

Comparator.

4.9.2

WINDOWED COMPARATOR

Figure 4-13 shows one approach to designing a

windowed comparator. The AND gate produces a logic

‘1’ when the input voltage is between VRB and VRT

(where VRT > VRB).

4.9.3

BISTABLE MULTI-VIBRATOR

A simple bistable multi-vibrator design is shown in

Figure 4-14. VREF needs to be between the power

supplies (VSS = GND and VDD) to achieve oscillation.

The output duty cycle changes with VREF.
