Typical Application

Description

The Microchip Technology, Inc. MCP6561/1R/1U/2/4

families of CMOS/TTL compatible comparators are

offered in single, dual, and quad configurations.

These comparators are optimized for low power 1.8V,

single-supply applications with greater than rail-to-rail

input operation. The internal input hysteresis eliminates

output switching due to internal input noise voltage,

reducing current draw. The push-pull output of the

MCP6561/1R/1U/2/4 family supports rail-to-rail output

swing, and interfaces with CMOS/TTL logic. The output

toggle frequency can reach a typical of 4 MHz (typical)

while limiting supply current surges and dynamic power

consumption during switching.

This family operates with single supply voltage of 1.8V

to 5.5V while drawing less than 100 µA/comparator of

quiescent current (typical).

MCP6561/1R/1U/2/4 4.0 APPLICATIONS INFORMATION The MCP6561/1R/1U/2/4 family of push-pull output comparators are fabricated on Microchip’s state-of-theart CMOS process. They are suitable for a wide range of high speed applications requiring low power consumption. 4.1 VDD Bond Pad VIN+ Bond Pad Bond Pad Input Stage VIN– Comparator Inputs 4.1.
PAGE 16
MCP6561/1R/1U/2/4 A significant amount of current can flow out of the inputs when the Common-mode voltage (VCM) is below ground (VSS); see Figure 2-32. Applications that are high impedance may need to limit the usable voltage range. 4.1.3 4.3.1 Figure 4-4 shows a non-inverting circuit for singlesupply applications using just two resistors. The resulting hysteresis diagram is shown in Figure 4-5. PHASE REVERSAL VDD The MCP6561/1R/1U/2/4 comparator family uses CMOS transistors at the input.
PAGE 17
MCP6561/1R/1U/2/4 4.3.2 INVERTING CIRCUIT Where: Figure 4-6 shows an inverting circuit for single-supply using three resistors. The resulting hysteresis diagram is shown in Figure 4-7.
PAGE 18
MCP6561/1R/1U/2/4 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 MCP6561/1R/1U/2/4 family’s bias current at +25°C (1 pA, typical).
PAGE 19
MCP6561/1R/1U/2/4 4.9 4.9.3 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. 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.
