11 Layout

11.1 Layout Guidelines

To create an accurate comparator application without hysteresis, maintain a stable power supply with minimized

noise and glitches, which can affect the high level input common-mode voltage range. To achieve this accuracy,

add a bypass capacitor between the supply voltage and ground. Place a bypass capacitor on the positive power

supply and negative supply (if available).

Note

If a negative supply is not being used, do not place a capacitor between the GND pin of the device

and system ground.
