APPLICATION INFORMATION

WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LVCMOS LEVELS

Figure 2A shows an example of the differential input that

can be wired to accept single ended LVCMOS levels. The

reference voltage level VBB generated from the device is

connected to the negative input. The C1 capacitor should

be located as close as possible to the input pin.
