Note 1: Fixed 50
resistor from REF OUT to REF IN and REF OUT to BIP OFF.
Note 2: VEE is optional and is only used to set the mode for the internal sample/hold. When not using VEE, the pin should be treated
as a no connect. If VEE is connected to 0 to -15 V, aperture delay (tAP) will increase from 20 ns (typ) to 4000 ns (typ).
Note 3: Available for external loads; external load should not change during conversion.
