LOGARITHMIC AND LOG RATIO AMPLIFIERS  
FEATURES  
DESCRIPTION  
The LOG112 and LOG2112 are versatile integrated circuits  
that compute the logarithm or log ratio of an input current  
relative to a reference current. VLOGOUT of the LOG112 and  
LOG2112 are trimmed to 0.5V per decade of input current,  
ensuring high precision over a wide dynamic range of input  
signals.  
EASY-TO-USE COMPLETE FUNCTION  
OUTPUT SCALING AMPLIFIER  
ON-CHIP 2.5V VOLTAGE REFERENCE  
HIGH ACCURACY: 0.2% FSO Over 5 Decades  
WIDE INPUT DYNAMIC RANGE:  
The LOG112 and LOG2112 features a 2.5V voltage refer-  
ence that may be used to generate a precision current  
reference using an external resistor.  
7.5 Decades, 100pA to 3.5mA  
LOW QUIESCENT CURRENT: 1.75mA  
WIDE SUPPLY RANGE: ±4.5V to ±18V  
PACKAGES: SO-14 (narrow) and SO-16  
Low DC offset voltage and temperature drift allow accurate  
measurement of low-level signals over the specified tem-  
perature range of –5°C to +75°C.
