Applications Circuits (Continued)

NON-INVERTING CURRENT-FEEDBACK INTEGRATOR

The circuit of Figure 6 achieves its high speed integration by

placing one of the LMH6715’s amplifiers in the feedback

loop of the second amplifier configured as shown.

LOW NOISE WIDE-BANDWIDTH TRANSIMPEDANCE

AMPLIFIER

Figure 7 implements a low noise transimpedance amplifier

using both channels of the LMH6715. This circuit takes

advantage of the lower input bias current noise of the non-

inverting input and achieves negative feedback through the

second LMH6715 channel. The output voltage is set by the

value of R

while frequency compensation is achieved

through the adjustment of R
