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 RF while frequency

compensation is achieved through the adjustment of RT.
