A good PCB layout for the LMH6601 involves keeping the input and output traces short and wide, using a solid ground plane, and placing the decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
The choice of output filter components depends on the specific application requirements. A good starting point is to use the recommended values in the datasheet, and then adjust based on the desired frequency response and impedance matching. TI also provides a Filter Design Tool to help with component selection.
The maximum power dissipation of the LMH6601 is 1.4W. To ensure it doesn't overheat, make sure to provide adequate heat sinking, such as a thermal pad or a heat sink, and keep the device within the recommended operating temperature range of -40°C to 85°C.
Yes, the LMH6601 can be used as a voltage-controlled amplifier by applying a control voltage to the VCTRL pin. The gain of the amplifier will vary in response to the control voltage, allowing for dynamic gain adjustment.
To ensure EMC with the LMH6601, follow good PCB design practices, such as using a solid ground plane, minimizing trace lengths, and using shielding or filtering to reduce electromagnetic radiation. Additionally, ensure that the device is properly decoupled and that the power supply is well-regulated.
