TPA8304 Overview
The TPA8304 is a logarithmic detector optimized for the measurement of low frequency signal power in fiber optic systems and offers a large dynamic range. Wide measurement range, accuracy and fast step response are achieved, which is very suitable for the requirement of optic system. The TPA8304 requires only a single positive supply of 5.
