Dual logarithmic converter is optimized for power monitoring in optical networking systems
Articles  
12/24/2003   Post a comment
A dual logarithmic converter from Analog Devices offers the functionality of two discrete converters on a single chip, providing designers of optical communication systems an alternative to using multiple individual logarithmic converters. The ADL5310 operates from a single supply as low as 3 V, and converts input current over a 100-dB dynamic range.
