The ADCMP603 comparator offers a programmable hysteresis
feature that can significantly improve accuracy and stability.
Connecting an external pull-down resistor or a current source
from the LE/HYS pin to GND varies the amount of hysteresis in
a predictable, stable manner. Leaving the LE/HYS pin
disconnected or driving it high removes the hysteresis. The
maximum hysteresis that can be applied using this pin is
approximately 160 mV. Figure 18 illustrates the amount of
hysteresis applied as a function of the external resistor value,
and Figure 9 illustrates hysteresis as a function of the current.
The hysteresis control pin appears as a 1.25 V bias voltage seen
through a series resistance of 7 kΩ ± 20% throughout the hysteresis
control range. The advantages of applying hysteresis in this manner
are improved accuracy, improved stability, reduced component
count, and maximum versatility. An external bypass capacitor is
not recommended on the HYS pin because it impairs the latch
function and often degrades the jitter performance of the device.
As described in the Using/Disabling the Latch Feature section,
hysteresis control need not compromise the latch function.

MINIMUM INPUT SLEW RATE REQUIREMENT
With the rated load capacitance and normal good PC Board
design practice, as discussed in the Optimizing Performance
section, these comparators should be stable at any input slew
rate with no hysteresis. Broadband noise from the input stage is
observed in place of the violent chattering seen with most other
high speed comparators. With additional capacitive loading or
poor bypassing, more persistent oscillations are seen. This
oscillation is due to the high gain bandwidth of the comparator
in combination with feedback parasitics in the package and PC
board. In many applications, chattering is not harmful since the
first cycle of the oscillation occurs close to V
CROSSOVER BIAS POINT
In both op amps and comparators, rail-to-rail inputs of this type
have a dual front-end design. Certain devices are active near the
VCC rail and others are active near the VEE rail. At some predeter-
mined point in the common-mode range, a crossover occurs. At
this point, typically VCC/2, the direction of the bias current reverses
and the measured offset voltages and currents change.
OS
.
The ADCMP603 slightly elaborates on this scheme. Crossover
points can be found at approximately 0.8 V and 1.6 V.
