The latched from dc to 6 GHz. It provides a programmable envelope event is held on the flip flop until a reset pulse is applied. threshold detection function. The RF input of the ADL5910 is dc-coupled, allowing operation The envelope threshold detection function compares the voltage down to arbitrarily low ac frequencies. It operates on a 3.3 V from an internal envelope detector with a user defined input supply and consumes 3.5 mA. Power-down mode reduces this voltage. When the voltage from the envelope detector exceeds current to 100 A when a logic low is applied to the ENBL pin. the user defined threshold voltage, an internal comparator The ADL5910 is supplied in a 3 mm 3 mm, 16-lead LFCSP for captures and latches the event to a set or reset (SR) flip flop. operation over the wide temperature range of 40C to +105C. The response time from the RF input signal exceeding the user 1 Protected by U.S. Patent 9,379,675.
