AD706
1 Hz, 4-Pole, Active Filter
Figure 7 shows the AD706 in an active filter application. An
important characteristic of the AD706 is that both the input bias
current, input offset current, and their drift remain low over
most of the op amp’s rated temperature range. Therefore, for
most applications, there is no need to use the normal balancing
resistor. Adding the balancing resistor enhances performance at
high temperatures, as shown by Figure 8.
