... Common-mode range extends from 3 V more positive than the negative supply more negative than the positive supply. Designed to cleanly drive and 100 pF loads, the AD648 will drive load with re- duced open-loop gain. Figure 21 shows the recommended crosstalk test circuit. A typi- cal value for crosstalk is – ...

... Figure 28. Photodiode Pre-Amp Errors Over Temperature DUAL PHOTODIODE PREAMP The performance of the dual photodiode preamp shown in Fig- ure 27 is enhanced by the AD648’s low input current, input voltage offset, and offset voltage drift. Each photodiode sources a current proportional to the incident light power on its surface. ...

... INSTRUMENTATION AMPLIFIER The AD648J’s maximum input current per amplifier makes it an excellent building block for the high input imped- ance instrumentation amplifier shown in Figure 29. Total cur- rent drain for this circuit is under 600 A. This configuration is optimal for conditioning differential voltages from high imped- ance sources ...

... This circuit ensures a 1% log conformance error over an input is the reverse satura- current range of 300 mA, with low level accuracy limited by the AD648’s input current. The low level input voltage accu- racy of this circuit is limited by the input offset voltage and drift of the AD648. ...
