The LMH6601 can operate off a single-supply or with dual supplies. The input CM capability of the parts (CMVR) extends all the way down to the V- rail to simplify single-supply applications. Supplies should be decoupled with low-inductance, often ceramic, capacitors to ground less than 0.5 inches from the device pins. TI recommends the use of ground plane, and as in most high-speed devices, it is advisable to remove ground plane close to device sensitive pins such as the inputs.
