AN-82: Understanding and Applying Voltage References
Reference noise is typically characterized over two frequency ranges: 0.1Hz to 10Hz for short-term, peak-to-peak drift, and 10Hz to 1kHz for total "wideband" RMS noise. Noise voltage is usually proportional to output voltage, so the output noise expressed in ppm is constant for all voltage options of any given reference.

Battery Voltage
The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage. In practice, the nominal battery voltage cannot be readily measured, but for practical battery systems (in which the overvoltages and non-ideal effects are low) the open circuit voltage is a good approximation to the nominal battery voltage.
