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.
