SLAS403A – NOVEMBER 2004 – REVISED DECEMBER 2004
The value of R3 in the previous equation can be reduced to increase the output current drive of U3. U3 can drive
circuit compensation capacitor C1 in the circuit is not suggested because of the change in the output impedance
Z
As shown in Equation 4, with matched resistors, Z
source. However, if unmatched resistors are used, Z
being a potential cause of oscillation. Therefore, by incorporating C1 into the circuit, possible oscillation problems
are eliminated. The value of C1 can be determined for critical applications; however, for most applications a
value of several pF is suggested.
