External Voltage Reference for Analog Read

Hey everyone. I am using a STM32F4 - Discovery board to read an analog value from a pressure sensor to convert it into depth. My problem is that the sensor that I need works with 0-5V and my STM32F4 works only with 3.3V. Is there any way to make the analog read module's reference an external 5V that I provide?
