NON-INVERTING CURRENT-FEEDBACK INTEGRATOR
The circuit of Figure 35 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 36 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_F while frequency
compensation is achieved through the adjustment of R_T.
