LOG101 LOG 101 SBOS242B – MAY 2002 – REVISED JUNE 2004 Precision LOGARITHMIC AND LOG RATIO AMPLIFIER FEATURES q EASY-TO-USE COMPLETE CORE FUNCTION q HIGH ACCURACY: 0.01% FSO Over 5 Decades q WIDE INPUT DYNAMIC RANGE: 7.5 Decades, 100pA to 3.5mA q LOW QUIESCENT CURRENT: 1mA q WIDE SUPPLY RANGE: ±4.5V to ±18V DESCRIPTION The LOG101 is a versatile integrated circuit that computes the logarithm or log ratio of an input current relative to a reference current. The LOG101 is tested over a wide dynamic range of input signals. In log ratio applications, a signal current can come from a photodiode, and a reference current from a resistor in series with a precision external reference.
