Analog inputs to “I” ADC. Nominal conversion range is 1.25V to
1.75V with GAIN pin low, or 1.0V to 2.0V with GAIN pin high.
Analog inputs to “Q” ADC. Nominal conversion range is 1.25V to
1.75V with GAIN pin low, or 1.0V to 2.0V with GAIN pin high.
Analog Reference Voltage input. The voltage at this pin should be
in the range of 0.8V to 1.5V. With 1.0V at this pin and the GAIN pin
low, the full scale differential inputs are 1 V
and the GAIN pin high, the full scale differential inputs are 2 V
This pin should be bypassed with a minimum 1 µF capacitor.
This is an analog output which can be used as a reference source
and/or to set the common mode voltage of the input. It should be
bypassed with a minimum of 1 µF low ESR capacitor in parallel with
a 0.1 µF capacitor. This pin has a nominal output voltage of 1.5V
and has a 1 mA output source capability.
Top of the reference ladder. Do not drive this pin. Bypass this pin
with a 10 µF low ESR capacitor and a 0.1 µF capacitor.
Bottom of the reference ladder. Do not drive this pin. Bypass this
pin with a 10 µF low ESR capacitor and a 0.1 µF capacitor.
