DC2767A

DC2767A is a LTC6754 high speed comparator with LVDS demonstration board. Demonstration circuit 2767A features the LTC®6754 high-speed rail to rail comparator in a QFN package with LVDS compatible outputs. The DC2767 input is AC-coupled for single-ended signal greater than 5MHz and up to 445MHz. The DC2767 outputs are AC-coupled 50 ohm source impedance for driving directly the 50 ohm inputs of a 1GHz or higher oscilloscope. The DC2767 has a supply connection for the LTC6754 rail to rail inputs and a separate supply connection for the QFN LTC6754 LVDS outputs. The LTC6754 includes 4.5mV of hysteresis to minimize instability.
