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 m a), 70mv (1ma) output voltages compatible with cmos logic systems

ha17901, ha17339 series 10 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 the circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator. figure 2 shows the waveforms generated by this circuit. + v cc v cc v cc 4.3k vout 100k r 75pf c 100k 100k 100k ha17901 figure 1 square-wave oscillator (2) horizontal: 5 v/div, vertical: 5 m s/div, v cc = 15 v (1) horizontal: 2 v/div, vertical: 5 m s/div, v cc = 5 v figure 2 operating waveforms
ha17901, ha17339 series 11 2. pulse generator 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 waveforms generated by this circuit. + ha17901 v cc v cc vout r 1 1m d 1 is2076 r 2 100k v cc 1m 1m 1m c 80pf d 2 is2076 figure 3 pulse generator horizontal: 5 v/div, vertical: 20 m s/div, v cc = 15 v horizontal: 2 v/div, vertical: 20 m s/div, v cc = 5 v figure 4 operating waveforms 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.

(vout ?v in ) (assuming vout = 15v) + v in < 6v r 1 r 1 + r 2 when +v in is lowered, the output will invert from high to low when +v in < 1.41v. therefore this circuit has a hysteresis of 7.65v. figure 8 shows the input characteristics.
