the phase lag caused by feedback resistor R
FB and input
capacitance C
IN. The value of CFB is determined by first
estimating C

Figure 2. Cancelling Feedback Phase Lag
Since a significant percentage of C
IN may be caused by board
layout, it is important to note that the correct value of C
FB may
change when changing from a breadboard to the final circuit
layout.
Typical Circuits
Some single-supply, rail-to-rail applications for which the
MIC7300 is well suited are shown in the circuit diagrams of
Figures 3 through 7.
