Description
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 50Ω transmission lines. Both outputs
are open emitter structures, requiring external pull-down
resistors. The recommended circuit is 50Ω 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.
