PRODUCTION DATA.
The LMH9226 operates on a common nominal 3.3-V supply voltage. The supply voltage is recommended to be isolated through the decoupling capacitors placed close to the device. Select capacitors with a self-resonant frequency near the application frequency. When multiple capacitors are used in parallel to create a broadband decoupling network, place the capacitor with the higher self-resonant frequency closer to the device.
The LMH9226 can be powered from a DC/DC converter or an LDO operating on a 3.3-V supply. A DC/DC converter provides the most power efficient way of generating the 3.3-V supply. However, care must be taken when using the DC/DC converter to minimize the switching noise from inductor chokes and adequate isolation must be provided between the analog and digital supplies.
