APPLICATION INFORMATION
The ADCMP361 is a low power comparator and reference
circuit featuring a 400 mV reference that operates from 1.7 V
to 5.5 V. The comparator is 0.275% accurate with a built-in
hysteresis of 9.3 mV. There are two outputs, one the inverse
of the other. This enables the ADCMP361 to be used as an
inverting or a noninverting comparator circuit. These open-
drain outputs are capable of sinking 40 mA.
COMPARATORS AND INTERNAL REFERENCE
The comparator has one input available externally; the other
comparator input is connected internally to the 400 mV reference.
The rising input threshold voltage of the comparators is designed
to be equal to that of the reference.
POWER SUPPLY
The ADCMP361 is designed to operate from 1.7 V to 5.5 V.
A 100 nF decoupling capacitor is recommended between VDD
and GND.
INPUTS
The comparator input is limited to the maximum VDD voltage
range. The voltage on these inputs can be above VDD but never
above the maximum allowed VDD voltage. When adding a
resistor string to the input, care must be taken when choosing
resistor values. This is due to the fact that the input bias current
will be in parallel with the bottom resistor, R2, of the input
resistor divider string. This bottom resistor must therefore be
chosen carefully in order to reduce the error introduced by this
bias current (see Figure 30).

OUTPUTS
The open-drain comparator outputs are limited to the
maximum specified VDD voltage range, regardless of the
VDD voltage. These outputs are capable of sinking up 40 mA.
ADDING HYSTERESIS
To prevent oscillations at the output caused by noise or slowly
moving signals passing the switching threshold, each compara-
tor has built-in hysteresis of approximately 9.3 mV. Positive
feedback can be used to increase hysteresis.
For the configuration shown in Figure 31, two resistors are used
to create different switching thresholds, depending on whether
the input signal is increasing or decreasing in magnitude. When
the input voltage is increasing, the threshold is above VREF, and
when it is decreasing, the threshold is below VREF.
