Supply Voltage Input, 3V to 5.5V. Bypass to GND with a 0.1µF capacitor.
Combined Current Source and A/D Positive Input for remote-diode channel. Do not leave DXP
floating; tie DXP to DXN if no remote diode is used. Place a 2200pF capacitor between DXP
and DXN for noise filtering.
Combined Current Sink and A/D Negative Input.
Open-drain output. Requires pull-up to VCC.
