HA17901, HA17339 Series
Quadruple Comparators
Description
The HA17901 and HA17339 series products are comparators designed for use in power or control systems.
These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced
power-supply current since the power-supply voltage is determined independently.
These comparators have the unique characteristic of ground being included in the common-mode input
voltage range, even when operating from a single-voltage power supply. These products have a wide range
of applications, including limit comparators, simple A/D converters, pulse/square-wave/time delay
generators, wide range VCO circuits, MOS clock timers, multivibrators, and high-voltage logic gates.
Features
Wide power-supply voltage range: 2 to 36V
Extremely low current drain: 0.8mA
Low input bias current: 25nA
Low input offset current: 5nA
Low input offset voltage: 2mV
The common-mode input voltage range includes ground.
Low output saturation voltage: 1mV (5
A), 70mV (1mA)
Output voltages compatible with CMOS logic systems

HA17901 Application Examples
The HA17901 houses four independent comparators in a single package, and operates over a wide voltage
range at low power from a single-voltage power supply. Since the common-mode input voltage range starts
at the ground potential, the HA17901 is particularly suited for single-voltage power supply applications.
This section presents several sample HA17901 applications.
HA17901 Application Notes
1. Square-Wave Oscillator

multivibrator. Figure 2 shows the waveforms generated by this circuit.

The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. (See
figure 3.) This allows the pulse width and the duty cycle to be set independently. Figure 4 shows the

3. Voltage Controlled Oscillator
In the circuit in figure 5, comparator A
1
operates as an integrator, A
2
operates as a comparator with
hysteresis, and A
3
operates as the switch that controls the oscillator frequency. If the output Vout1 is at
the low level, the A
3
output will go to the low level and the A1 inverting input will become a lower
level than the A1 noninverting input. The A1 output will integrate this state and its output will increase
towards the high level. When the output of the integrator A
1
exceeds the level on the comparator A
2
inverting input, A
2
inverts to the high level and both the output Vout1 and the A
3
output go to the high
level. This causes the integrator to integrate a negative state, resulting in its output decreasing towards
the low level. Then, when the A
1
output level becomes lower than the level on the A
2
noninverting
input, the output Vout1 is once again inverted to the low level. This operation generates a square wave
on Vout1 and a triangular wave on Vout2.

5. Noninverting Comparator (with Hysteresis)
Assuming +V
IN
is 0V, when V
REF
is applied to the inverting input, the output will go to the low level
(approximately 0V). If the voltage applied to +V
IN
is gradually increased, the output will go high when
the value of the noninverting input, +V
IN
R
2
/(R
1
+ R

), exceeds +V
REF
. Next, if +V
IN
is gradually
lowered, Vout will be inverted to the low level once again when the value of the noninverting input,
(Vout V
IN
)
R
1
/(R
1
+ R
2
), becomes lower than V
REF
. With the circuit constants shown in figure 7,
assuming V
CC
= 15V and +V
REF
= 6V, the following formula can be derived, i.e. +V
IN
10M/(5.1M +
10M)
>
6V, and Vout will invert from low to high when +V
IN
is > 9.06V.
