The LM4040 has two very high precision shunt-type voltage references with 750 ohm biasing resistors. One is 2.048V (great for 3.3V reference systems) and the other is 4.096 (great for 5V). Both are 0.1% accuracy. Using is easy, just power with about 5V-12V, or 3V if you want only the 2V reference to work. Then measure the voltage on the output.
