AD8304 Logarithmic Detector Light Detector 160dB 100pA-10mA Module

Introduction AD8304 is a single chip logarithmic detector optimized for low frequency signal power measurement in fiber optic systems It uses advanced transconductivity technology to provide a wide dynamic range that is diverse and easy to use Using proprietary design technology and precise laser adjustment the device can also achieve wide measurement range and high precision characteristics In most applications only a 5 V single power supply VP is required but a 3 0 V to 5 5 V power supply can also be used the additional use of a negative power supply VN is beneficial for some applications When using a low supply voltage the logarithmic slope can be easily changed to fit the usable range Low quiescent current and chip disable features are beneficial for battery powered applications Features Optimized for fiber photodiode interface8 level 10 times rangeSingle power supply 7 15 V with voltage regulator chip Complete high temperature stabilityThe output provides unipolar bipolar or three pole low pass filteringSmall 14 pin TSSOP packagePrecision laser adjustment Logarithmic slope 10 mV dB VLOG pin Basic log intercept 100 pAEasily adjust slope and interceptOutput bandwidth 10 MHzSlew rate 15 V μsLow power consumption quiescent current is about 4 5 mA when enabled Product dimensions length 48mm width 32mmWeight 10 gramsPackage includes 1 x Module
