Analog Input
The analog input to the A/D converter is supplied
through the BNC coaxial connector labeled AIN.
Analog input polarity is controlled by the first
position switch on the DIP-switch, SW-1. If it is
on, the input is unipolar ranging from GND to
VREF. If the switch is off, the input range is bi-
polar with the magnitude of the reference voltage
defining both zero- and full-scale (
±VREF).
The A/D converter’s internal analog input buffer
requires a source impedance of less than 400
at 1MHz for stability. Acquisition and throughput
are specified assuming a dc source impedance of
less than 200
. Infinitely large dc source imped-
ances can be accommodated by adding capaci-
tance (typically 1000pF) from the analog input to
ground. However, high dc source resistances de-
grade acquisition time and consequently through-
put.
