Ground.
Analog +5 V power supply.
Internal bandgap voltage reference (nominally +2.5 V).
Input to reference amplifier. Voltage reference for ADC is connected here.
Bandwidth Select. NC = 130 MHz nominal. +V
D
= 50 MHz nominal.
Complementary analog input pin (Analog input bar).
Analog input pin.
Encode clock input to ADC. Internal T/H is placed in hold mode (ADC is encoding)
on rising edge of encode signal.
Out of range signal. Logic “0” when analog input is in nominal range. Logic “1” when
analog input is out of nominal range.
Most significant bit of ADC output.
Digital output bits of ADC.
Digital output power supply (only used by digital outputs).
Digital output bits of ADC.
Least significant bit of ADC output.
