GENERAL DESCRIPTION
●The ADL5303is a monolithic logarithmic detector optimized for the measurement of low frequency signal power in fiber optic systems and offers a large dynamic range in a versatile and easily used form. Wide measurement range and accuracy are achieved using proprietary design and precise laser trimming.
●FEATURES
●Optimized for fiber optic photodiode interfacing
●8 full decades of range
●Law conformance: 0.1 dB from 1 nA to 1 mA
●Single-supply operation: 3.0 V to 5.5 V
●Complete and temperature stable
●Accurate laser trimmed scaling
●Logarithmic slope of 10 mV/dB (at the VLOG pin)
●Basic logarithmic intercept at 100 pA
●Easy adjustment of slope and intercept
●Output bandwidth of 10 MHz, 15 V/μs slew rate
●Miniature 16-lead package (LFCSP)
