IC Voltmeter 4-1/2 Digit

Hi all,

I have the following problem, I need to convert the linear range from

0 to 5 Volts in a measure of weight (from 0 to 9999 tons) displayed in a 4 -1/2 digit 7 segments) display and I was wondering if a Voltmeter rightly tuned could do at job. Does anyone know any IC voltmeter able to drive a 4-1/2 digit (or more)?

Thanks, Ciao Eugenio
