10-bit high-speed 3.0 to 5.25 V
analog-to-digital converter
The analog and digital supplies should be separated and decoupled.
The external voltage reference 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

(2) Pins 8, 12, 13, 17, 24 and 32 should be connected to the closest ground pin in order to prevent noise influence.
