9 / 19 page TL441EP LOGARITHMIC AMPLIFIER SGLS268 − OCTOBER 2004 9 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Output Levels Differential-output-voltage levels are low, generally less than 0.6 V. As demonstrated in Figure 11, 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 also can be adjusted by positioning the offset of the output buffer. Circuits Figure 11 through Figure 18 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. 1.4 1.2 1.0 0.8 0.6 0.4 0.2 0 − 0.2 10 − 4 10 −3 10 −2 10 −1 101 1 TYPICAL TRANSFER CHARACTERISTICS Adjusted for Increased Slope and Offset Adjusted For Minimum Slope With Zero Offset Input Voltage − V Input A1 A2 Y Y 1/2 TL441 Origin Slope Output GND + − + − Figure 11.
