The LTC6752 is a family of very high speed comparators capable of supporting toggle rates up to 280MHz. These comparators exhibit low propagation delays of 2.9ns, and fast rise/fall times of 1.2ns. There are a total of 5 members in the LTC6752 family, with different options for separate input and output supplies, shutdown, output latch, adjustable hysteresis, complementary outputs, and package.
The LTC6752 comparators have rail-to-rail inputs that operate from 2.45V, up to 3.5V or 5.25V, depending on the option. The outputs are CMOS and the separate supply options can operate down to 1.71V, allowing for directly interfacing to 1.8V logic devices.
The low propagation delay of only 2.9ns combined with low dispersion of only 1.8ns (10mV to 125mV overdrive variation) makes these comparators an excellent choice for critical timing applications. Similarly, the fast toggle rate and the low jitter of 4.5ps RMS (100mVP-P, 100MHz input) make the LTC6752 family ideally suited for high frequency line driver and clock recovery circuits.
