DC2261A-B

DC2261A-B demonstration circuit features the LT6119-2, a high side current sense amplifier with comparators and a 400mV reference. The demo board circuit amplifies the voltage across an on-board current sense resistor, to provide a precision unipolar voltage output that is proportional to the sensed current. The board has two on-board comparators with latching outputs and an integrated 400mV reference that sets the threshold for the comparators. The DC2261A-B (LT6119-2) has two inverting inputs available. The current sense gain and current fault limits are set by on board resistors. The default gain is set at 10V/A and the comparators are set to trip at current thresholds of 50mA and 300mA.
