LMH6654, LMH6655 SNOS956D – JUNE 2001 – REVISED MARCH 2013 www.ti.com The PCB should have a ground plane covering all unused portion of the component side of the board to provide a low impedance path. All trace lengths should be minimized to reduce series inductance. Supply bypassing is required for the amplifiers performance. The bypass capacitors provide a low impedance return current path at the supply pins. They also provide high frequency filtering on the power supply traces.

LMH6654, LMH6655 www.ti.com SNOS956D – JUNE 2001 – REVISED MARCH 2013 POWER DISSIPATION The package power dissipation should be taken into account when operating at high ambient temperature and/or high power dissipative conditions. In determining maximum operable temperature of the device, make sure the total power dissipation of the device is considered; this power dissipated in the device with a load connected to the output as well as the nominal dissipation of the op amp.

Noise Model with Rf || Rg = Rseq eni = en2 + 2 (in · RSeq)2 + 4kT (2RSeq) (4) If bias current cancellation is not a requirement, then Rf || Rg does not need to equal Rseq. In this case, according to Equation 3, Rf and Rg should be as low as possible in order to minimize noise.
