Notes:
1. VAA and VAA_PIX must all be at the same potential to avoid excessive current draw. Care must be
taken to avoid excessive noise injection in the analog supplies if all three supplies are tied together.
2. The imager operates in this temperature range, but image quality may degrade if it operates
beyond the functional operating temperature range.
3. Image quality is not guaranteed at temperatures equal to or greater than this range.

Note:
DAC_POS, DAC_NEG, and DAC_REF are loaded with resistors to simulate video output driving into
a low pass filter and achieve a full output swing of 1.4V. Their resistor loadings may be different
from the loadings in a real single-ended or differential-ended video output system with an actual
receiving end. Please refer to the Developer Guide for proper resistor loadings.
