The ADS7817
’
s V
input current is proportional to conversion rate. A
conversion rate of 10kS/s or slower assures enough current to turn on the
reference diode. Converter input range is
±
1.2V. Output swing limitation of
INA126 limits the A/D converter to somewhat greater than 11 bits of range.
A similar instrumentation amplifier, INA125, provides
an internal reference voltage for sensor excitation
and/or A/D converter reference.
