The HFA-0003/0003L are monolithic, ultra high speed,
voltage comparators. These comparators combine a low
input offset voltage (1.0mV) with a low propagation delay
(2.0ns) to achieve a large dynamic input range. The low off-
set voltage also makes these comparators ideally suited for
high speed, precision analog-to-digital processing applica-
tions. The circuits have differential analog inputs, and pro-
vide complementary, ECL compatible (10K and 100K) logic
outputs. The outputs are capable of supplying the current
required by terminated 50⦠transmission lines. Both outputs
are open emitter structures, requiring external pull-down
resistors. The recommended circuit is 50⦠connected to -
2.0V, but any equivalent ECL termination circuit may be
used.
The HFA-0003L is a latched version of the HFA-0003. The
latch function allows the HFA-0003L to operate in sample-
hold or track-hold modes, when synchronous detection is
required. The Latch Enable (LE) input can be driven by a
standard ECL gate. See the Applications section for more
information on this feature.
The HFA-0003L also has an additional feature, user
programmable hysteresis. By connecting a resistor from the
HYS pin to GND the user can select up to 20mV of input
hysteresis. See the Applications section for more informa-
tion on this feature.
The HFA-0003 is pin compatible with the MAX9690, and
SP9680 while providing improved performance. The HFA-
0003L is pin compatible with the MAX9685, AD96685,
SP9685, HCMP96850, and the VC7695 while providing
improved performance.
