>The LT1720** works on a 3.3v single supply, and has internal
>hysteresis. Just ground one input, ground the other through a
>resistor, and attach your AC-coupled signal (best if you can use
>equal resistors to ground on the two inputs, but if the signal
>termination is 50 ohms the other input can be 0 ohms to ground; even
>1k ohm would probably be OK).
>Note that the LT1720 is specified for inputs to 100mV below V-
>(ground, in this case) and your 200mVpp signal pushes it right to
>the limit. A bit of attenuation is probably a good idea.
>** The 1720 is a dual comparator, so you'd have an extra to use or
>ignore. Alternatively, the 1719 is a single with extra features
>that you could ignore. Either should work well in your application.
