HA17339A Series
Quadruple Comparators
REJ03D0675-0300
Rev.3.00
Mar 10, 2006
Description
The HA17339A series products are comparators designed for general purpose, especially for power control systems.
These ICs operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-
supply current since the supply current is independent of the supply voltage.

These comparators have the merit which ground is included in the common-mode input voltage range at a single-
voltage power supply operation. 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 36 V
• Very low supply current
: 0.8 mA Typ.
• Low input bias current
: 25 nA Typ.
• Low input offset current
: 5 nA Typ.
• Low input offset voltage
: 2 mV Typ.
• The common-mode input voltage range includes ground
• Output voltages compatible with CMOS logic systems

4. Basic Comparator
The circuit shown in figure 6 is a basic comparator. When the input voltage VIN exceeds the reference voltage VREF,
the output goes to the high level.

5. Noninverting Comparator (with Hysteresis)
www.DataSheet4U.cAosmsuming +VIN is 0V, when VREF is applied to the inverting input, the output will go to the low level (approximately
0V). If the voltage applied to +VIN is gradually increased, the output will go high when the value of the noninverting
input, +VIN × R2/(R1 + R2), exceeds +VREF. Next, if +VIN is gradually lowered, Vout will be inverted to the low
level once again when the value of the noninverting input, (Vout – VIN) × R1/(R1 + R2), becomes lower than VREF.
With the circuit constants shown in figure 7, assuming VCC = 15V and +VREF = 6V, the following formula can be
derived, i.e. +VIN × 10M/(5.1M + 10M) > 6V, and Vout will invert from low to high when +VIN is > 9.06V.

(Assuming Vout = 15V)
When +VIN is lowered, the output will invert from high to low when +VIN < 1.41V. Therefore this circuit has a
hysteresis of 7.65V. Figure 8 shows the input characteristics.
