Overview
ICL8048 Data Sheet August 1999 File Number 2865.
2 Log Amplifier The ICL8048 is a monolithic logarithmic amplifier capable of handling six decades of current input, or three decades of voltage input.
It is fully temperature compensated and is nominally designed to provide 1V of output for each decade change of input.
For increased flexibility, the scale factor, reference current and offset voltage are externally adjustable.
