5.1 Ambient Light Cancellation

The LMH34400 device features an input DC current cancellation circuit that is designed to remove any DC current that is present from a typical current input device such as a photodiode. This feature can be enabled or disabled using the ALC jumper, or by populating R4 with a zero-ohm resistor. By default, the DC current cancellation circuit is enabled.
