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 V. Low quiescent current and chip disable facilitate use in batteryoperated applications.
