1 / 16 page 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 Precision LOGARITHMIC AND LOG RATIO AMPLIFIER 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. The output signal at VOUT is trimmed to 1V per decade of input current allowing seven decades of input current dynamic range. Low DC offset voltage and temperature drift allow accurate measurement of low-level signals over a wide environmental temperature range. The LOG101 is specified over the tem- perature range –5 °C to +75°C, with operation over –40 °C to +85°C. APPLICATIONS q LOG, LOG RATIO COMPUTATION: Communication, Analytical, Medical, Industrial, Test, and General Instrumentation q PHOTODIODE SIGNAL COMPRESSION AMPS q ANALOG SIGNAL COMPRESSION IN FRONT OF ANALOG-TO-DIGITAL (A/D) CONVERTERS LOG101 www.ti.com PRODUCTION DATA information is current as of publication date.
