Improved frequency response is achieved by indirectly driving capacitive loads, as shown in Figure 61.
Compensated to handle a 330pF capacitive load.
Figure 61. LMC6482 Noninverting Amplifier
R1 and C1 serve to counteract the loss of phase margin by feeding forward the high frequency component of the
output signal back to the amplifiers inverting input, thereby preserving phase margin in the overall feedback loop.
The values of R1 and C1 are experimentally determined for the desired pulse response. The resulting pulse
response can be seen in Figure 62.
