The LOG101AIDR is a precision logarithmic amplifier from Texas Instruments designed for high accuracy and wide input dynamic range. It operates over a temperature range of -40¬8C to +85¬8C and features a low quiescent current of 1mA. The device can handle input currents from 100pA to 3.5mA, providing a dynamic range of 7.5 decades. The output voltage is trimmed to 1V per decade of input current, ensuring accurate log ratio computations. It is suitable for applications in communication, analytical, medical, and industrial instrumentation, as well as for photodiode signal compression and analog signal processing before analog-to-digital conversion. The LOG101AIDR is housed in an 8-pin SOIC package and is specified for operation with supply voltages ranging from ¬±4.5V to ¬±18V.
