ADL5513 Datasheet PDF

●GENERAL DESCRIPTION

●The ADL5513 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in

●either measurement or controller modes.
