Application Information

Detailed Description

LMV331/LMV393 are low-voltage single/dual general- purpose comparators. They have a single supply operating voltage range from 2.7V to 5.5V;

the common mode input voltage range extends from -0.1V below the negative supply to within 0.8V of the positive supply.

The LMV331/393 series is built using the BiCMOS process with bipolar input and output stages for improved noise performance. It is a cost-

effective solution for portable consumer products where space, low voltage, low power and price are the primary specification in circuit design.

Basic Comparator

A basic comparator circuit is used for converting analog signal to digital output. The LMV331/393 has open-collector output structure, which

required a pull-high resistor to positive supply voltage for the output to switch properly. When the internal output transistor is off, the output voltage

will be pulled up to the external positive voltage.

The output pull- up resistor should be chosen high enough so as to avoid excessive power dissipation, yet low enough to supply enough drive to

switch whatever load circuitry is used on the comparator output. On the LMV331/393 the pull-up resistor should range between 1KΩ to 10KΩ.

Power Supply Bypassing

For better performance, power supply bypass capacitor is necessary. For a single-supply operation system, a minimum of 0.1µF bypass capacitor

should be recommended to place as close as possible between V_CCpin and GND.
