DC1699A-B

DC1699A-B demonstration circuit features the LT®6108, a high-side current sense amplifier with a comparator and a 400mV reference. The demo board circuit amplifies the voltage across an onboard current sense resistor, to provide a precision unipolar voltage output that is proportional to the sensed current. The board has one onboard comparator and an integrated 400mV reference that sets the threshold for the comparator. The DC1699A-B (LT6108-2) has a non-latching comparator. The current sense gain and current fault limits are set by onboard resistors. The gain is set at 25V/V and the comparator is set to trip at a current threshold of 500mA.

• Input voltage range from 2.7V to 60V
• 250mV measured output signal (ILOAD = 100mA)
• 650μA quiescent current (VIN = 12V)
