MCP6566/6R/6U/7/9 4.0 APPLICATIONS INFORMATION The MCP6566/6R/6U/7/9 family of open-drain output comparators are fabricated on Microchip’s state-of-the-art CMOS process. They are suitable for a wide range of high speed applications requiring lowpower consumption. 4.1 Comparator Inputs 4.1.1 NORMAL OPERATION The input stage of this family of devices uses two differential input stages in parallel.
MCP6566/6R/6U/7/9 It is also possible to connect the diodes to the left of the resistors R1 and R2. In this case, the currents through the diodes D1 and D2 need to be limited by some other mechanism. The resistor then serves as in-rush current limiter; the DC current into the input pins (VIN+ and VIN–) should be very small. 4.3.1 NON-INVERTING CIRCUIT Figure 4-4 shows a non-inverting circuit for single-supply applications using just two resistors. The resulting hysteresis diagram is shown in Figure 4-5.
MCP6566/6R/6U/7/9 4.3.2 INVERTING CIRCUIT Where: R2 R3 R 23 = ------------------R2 + R3 Figure 4-6 shows an inverting circuit for single-supply using three resistors. The resulting hysteresis diagram is shown in Figure 4-7.
MCP6566/6R/6U/7/9 4.6 PCB Surface Leakage 4.7 In applications where low input bias current is critical, PCB (Printed Circuit Board) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 1012. A 5V difference would cause 5 pA of current to flow. This is greater than the MCP6566/6R/6U/7/9 family’s bias current at +25°C (1 pA, typical).
MCP6566/6R/6U/7/9 4.9 Typical Applications 4.9.1 4.9.3 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. BISTABLE MULTIVIBRATOR A simple bistable multivibrator design is shown in Figure 4-14. VREF needs to be between the power supplies (VSS = GND and VDD) to achieve oscillation.
