ADL5309 General Description

The ADL5309 contains dual monolithic logarithmic transimpedance amplifiers that are optimized for measuring low-frequency and wide dynamic range optical signal power in fiber optic systems. The device produces highly accurate, temperature compensated output voltages that are proportional to the loga.
