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 (5µA), 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 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.

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.

3. Voltage Controlled Oscillator In the circuit in figure 5, comparator A1 operates as an integrator, A2 operates as a comparator with

hysteresis, and A3 operates as the switch that controls the oscillator frequency. If the output Vout1 is at the low level, the A3 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 A1 exceeds the level on the comparator A inverting input, A2 inverts to the high level and both the output Vout1 and the A3 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 A1 output level becomes lower than the level on the A2 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.
