LMH6723/LMH6724/LMH6725 offers a unique combination of high speed and low quiescent supply current making it suitable for a wide range of battery powered and portable applications that require high performance.

LMH6723, LMH6724, LMH6725 SNOSA83H – AUGUST 2003 – REVISED APRIL 2013 www.ti.com Figure 37 shows the LMH6723/LMH6724/LMH6725's frequency response as RF is varied (RL = 100Ω, AV = +2). This plot shows that an RF of 800Ω results in peaking. An RF of 1200Ω gives near maximal bandwidth and gain flatness with good stability. Since each application is slightly different it is worth some experimentation to find the optimal RF for a given circuit. In general a value of RF that produces ~0.

RF vs. Inverting Gain ACTIVE FILTERS When using any current feedback operational amplifier as an active filter it is necessary to be careful using reactive components in the feedback loop. Reducing the feedback impedance, especially at higher frequencies, will almost certainly cause stability problems.

The charts "Suggested ROUT vs. Cap Load" give a recommended value for selecting a series output resistor for mitigating capacitive loads. The values suggested in the charts are selected for .5 dB or less of peaking in the frequency response.
PAGE 17
LMH6723, LMH6724, LMH6725 www.ti.com SNOSA83H – AUGUST 2003 – REVISED APRIL 2013 When higher currents are required than a single amplifier can provide, the circuit of Figure 43 can be used. Although the example circuit was intended for the LMH6725 quad op amp, higher thermal efficiency can be obtained by using four separate SOIC op amps. Careful attention to a few key components will optimize performance from this circuit.

LMH6723, LMH6724, LMH6725 SNOSA83H – AUGUST 2003 – REVISED APRIL 2013 www.ti.com POWER DISSIPATION Follow these steps to determine the maximum power dissipation for the LMH6723/LMH6724/LMH6725: 1. Calculate the quiescent (no-load) power: PAMP = ICC * (VS) where VS = V+ - V2. Calculate the RMS power dissipated in the output stage: PD (rms) = rms ((VS-VOUT)*IOUT) where VOUT and IOUT are the voltage and current of the external load and Vs is the supply voltage. 3.
