Low input bias current: The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. 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 IC operate from a single hx17339 voltage over a wide range of voltages, and feature a reduced power-supply current since the power-supply voltage is determined independently.

Electrical Characteristics 1 V. When the output of the integrator A. Inverting Comparator with Hysteresis.

This causes the integrator to integrate a negative state, resulting in its output decreasing towards the low level. In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. The A1 output will integrate this state and its output will increase towards the high level. This section presents several sample HA applications. The circuit shown in figure 6 is a basic comparator.
