8-bit, 40 Msps 2.7 to 5.5 V universal
analog-to-digital converter
The analog and digital supplies should be separated and decoupled.
The external voltage generator must be built such that a good supply voltage ripple rejection is achieved with respect to the LSB value. Eventually, the
reference ladder voltages can be derived from a well regulated V
