DESCRIPTION
The LTC®6752 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, adjust-
able 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.
