DEVICE OPERATION

INPUT INTERFACING

The LMH0202 accepts either differential or single-ended input. The inputs are self-biased, allowing for simple AC

or DC coupling. DC-coupled inputs must be kept within the specified common-mode range. SDI and SDI are self-

biased at approximately 2.1V with VCC = 3.3V. Figure 2 shows the differential input stage for SDI and SDI.
