Comparator for sensor

Hi,

I am building an application that needs to beep when the voltage output from the sensor device is less than 0.8 Volts. I am not sure what would be the right design that I can use for the buzzer to beep. The voltage for the sensor is 5 V DC supply. Should I consider using 741/LM series?

Regards,
Mani
