A new high-side monitor provides a compact solution for the commonproblem of interfacing an optical power monitoring device, such as a logarithmic amplifier, to the cathode-side of a PIN photodiode.

Analog Devices is introducing a high-side monitor that provides a compact solution for the common and often challenging problem of interfacing an optical power monitoring device, such as a logarithmic amplifier, to the cathode-side of a PIN photodiode The ADL5315 mirrors the current at the cathode at a 1:1 ratio over a six-decade range, producing an output equal to the reference current monitored
