I am designing a high speed circuit about differential buffers ,and in this circuit I need a kind of Low Power and High speed Differential ADC Driver Chip. So I choose the ADA4932-1 from the products of ADI. However, I browse the datasheet again and again . If the input signals are differential signals, I can not find the Calculation formula of the power of load drive . Now I can not choose a suitable power to drive the ADA4932-1. Can you offer me the Calculation formula ? Please write to me soon,thank you!
