Logarithmic Amplifier Voltage Output 1. The output scale factor of LOGV1 is 0.25V/decade.
Offset Adjust Input. When operating from a single power supply, current applied to OSADJ adjusts
the output offset voltage (see the Output Offset section).
Scale Factor Input. Adjust the output scale factor for LOGV2 using a resistive divider (see the Scale
Factor section).
