Analog & Power: Dual Logarithmic Converter Watches Optical-Network Power

Offering the functionality of two discrete converters on one chip, the ADL5310 dual logarithmic converter gives designers of optical communications systems an alternative to multiple devices. The ADL5310 operates from a single supply of as little as 3 V to convert input currents over a 100-dB dynamic range. Containing two independent signal channels for photodiode interfacing, the device allows the transfer-function constants (slope and intercept) to be individually configured for each channel. Packaged in a 24-pin LFCSP, it costs $11.33 each in lots of 1000.
