Overview
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. The LOG112 and LOG2112 features a 2.5V voltage reference that may be used to generate a precision current reference using an external resistor. Low DC offset voltage and temperature drift allow accurate measurement of low-level signals over the specified temperature range of -5°C to +75°C.
Applications
- LOG, LOG RATIO: Communication, Analytical, Medical, Industrial, Test, General Instrumentation
- PHOTODIODE SIGNAL COMPRESSION AMP
- ANALOG SIGNAL COMPRESSION IN FRONT OF ANALOG-TO-DIGITAL (A/D) CONVERTER
- ABSORBANCE MEASUREMENT
- OPTICAL DENSITY MEASUREMENT
Key features
- 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: 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
