TPA8304 - 140dB Range Logarithmic Converter

Datasheet Summary

Description

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.

Features

  • 7 full decades of range: 1nA to 10mA.
  • Law conformance error: 0.2 dB from 10nA to 10mA.
  • Fast step response: raising 0.2μs, falling 5μs for 10nA to 10μA input on INPT.
  • Basic logarithmic intercept at 100 pA.
  • Logarithmic slope of 200 mV/20dB (at the VLOG pin).
  • Optimized for fiber optic photodiode interfacing.
  • Single-supply operation: 4.5 V to 5.5 V.
  • Power down mode.
