Product Summary

The LOG101AID is a logarithmic and log ratio amplifier. The LOG101AID is a versatile integrated circuit that computes the logarithm or log ratio of an input current relative to a reference current. The LOG101AID 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.

Parametrics

LOG101AID absolute maximum ratings: (1)Supply Voltage, V+ to V-: 36V; (2)Input Voltage: V- (-0.5) to V+ (+0.5V); (3)Input Current: ±10mA; (4)Output Short-Circuit: Continuous; (5)Operating Temperature: -40℃ to +85℃; (6)Storage Temperature: -55℃ to +125℃; (7)Junction Temperature: +150℃; (8)Lead Temperature (soldering, 10s): +300℃.

Features

LOG101AID features: (1)Easy-to-use complete core function; (2)High accuracy: 0.01% FSO Over 5 Decades; (3)Wide input dynamic range: 7.5 Decades, 100pA to 3.5mA; (4)Low quiescent current: 1mA; (5)Wide supply range: ±4.5V to ±18V.
