Intersil ICL8049
The ICL8049 is a monolithic antilogarithmic amplifier that is fully temperature compensated and is nominally designed to provide 1 decade of output voltage for each 1V change of input voltage. For increased flexibility, the scale factor, reference current and offset voltage are externally adjustable. ICL8049 OFFSET AND SCALE FACTOR ADJUSTMENT ICL8049 Detailed Description The ICL8049 relies on the same logarithmic properties of the transistor as the ICL8048.| Part No. | ICL8049 |
