LOGARITHMIC AMPLIFIER

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
output levels
Differential-output-voltage levels are low, generally less than 0.6 V. As demonstrated in Figure 12, the output
swing and the slope of the output response can be adjusted by varying the gain by means of the slope control.
The coordinate origin may also be adjusted by positioning the offset of the output buffer.
circuits
Figures 12 through 19 show typical circuits using this logarithmic amplifier. Operational amplifiers not otherwise
designated are TLC271. For operation at higher frequencies, the TL592 is recommended instead of the
TLC271.
