ADL5303ACPZ-R7 Logarithmic Amplifier, Fiber-Optic Signal Monitoring IC
1. Overview
The Analog Devices ADL5303ACPZ-R7 is a monolithic logarithmic amplifier optimized for high-precision optical power measurement and low-frequency signal detection in fiber-optic systems. Designed for applications requiring exceptional dynamic range and accuracy, this device features a 16-lead LFCSP-16 package, operating across a 3 V to 5.5 V supply voltage range. It delivers a logarithmic output response with a default slope of 10 mV/dB and an intercept at 100 pA, enabling precise measurements from 100 pA to 10 mA (160 dB dynamic range). Its adaptive biasing scheme minimizes dark current at low light levels, while the integrated low-offset JFET amplifier ensures stable performance across temperature variations.
