... Figure 25. Settling Time Test Circuit The upper trace of the oscilloscope photograph of Figure 26 shows the settling characteristic of the AD544. The lower trace represents the input to Figure 27. The AD544 has been designed for fast settling to 0.01%, however, feedback components, cir- cuit layout and circuit design must be carefully considered to obtain optimum settling time. Figure 26. Settling Characteristic Detail– ...

... AD542/AD544/AD547 BiFET Application Hints APPLICATION NOTES The BiFET series was designed for high performance op amp applications that require true dc precision. To capitalize on all of the performance available from the BiFETs there are some practical error sources that should be considered. The bias currents of JFET input amplifiers double with every 10 C increase in chip temperature ...

... AD542/AD544/AD547 This particular log ratio circuit is free from the dynamic prob- lems that plague many other log circuits. The –3 dB bandwidth is 50 kHz over the top 3 decades, 100 nA to 100 A, and de- creases smoothly at lower input levels. This circuit needs no ad- ditional frequency compensation for stable operation from input current sources, such as photodiodes, that may have 100 pF of shunt capacitance ...
