Description
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
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)
