GENERAL DESCRIPTION

The ADL5306? is a low cost microminiature logarithmic converter optimized for determining optical power in fiber optic systems. The ADL5306 is derived from the AD8304 and AD8305 translinear logarithmic converters. This family of devices provides wide measurement dynamic range in a versatile and easy-to-use form. A single-supply voltage between 3 V and 5.5 V is adequate; dual supplies may optionally be used. Low quiescent current (5 mA typical) permits use in battery-operated applications.
