These devices are designed for rail-to-rail input and output application. The AZV3001 device consumes only 6µA supply current while achieving a typical propagation delay 0.8µS under 20mV input overdrive condition. These family comparators are guaranteed to operate at low supply voltage 1.6V to 5.5V. The AZV3001 /2 series have a typical internal hysteresis of 9.0mV. This allows for greater noise immunity and clean output switching. The Output Stage The AZV3001 and AZV3002 feature a push-pull output, which have a complementary P- and N-Channel output stage. When the output switches, there is a direct patch between VCC and VEE, causing increased output sinking or sourcing current during the transition. Following the transition the output current decreases and supply current returns to 6µA, thus maintaining low power consumption. Many comparators consume orders of magnitude more current during switching than during steady-state operation. However, with this family of comparators, the supply current change during an output transition is extremely small. The graph of Supply Current vs. Output Transition Frequency shows the minimal supply current increase as the output switching frequency approaches 1KHz. In batterypowered applications, this characteristic results in a substantial increase in battery life. VCC IN+ Output IN- VEE Figure 13 AZV3001/2 Complementary Output Configuration Internal Input Hysteresis Voltage (VHYST) Many comparators oscillate in the linear region of operation because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is equal to, or very close to the voltage on the other input. The AZV3001/2 have internal 9mV (Typ.) hysteresis to counter parasitic effects and noise. The hysteresis in a comparator creates two trip points: one for the rising input voltage (VHYST+) and one for the falling input voltage (VHYST-). The difference between the trip points is the hysteresis (VHYST). When the comparator’s input voltage are equal, the hysteresis effectively causes one comparator input to move quickly past the other, thus taking the input out of the region where oscillation occurs. Figure 1 illustrates the case in which VIN- has a fixed voltage applied, and VIN+ is varied. If the inputs were reversed, the figure would be the same, except with an inverted output.

This voltage is added to VTH to formal the actual trip point at which the comparator must respond in order to change output states. VHYST: internal hysteresis (or trip window) that is designed to produce comparator sensitivity to noise.

The AZV3001 and AZV3002 are designed to prevent phase inversion when the input pins exceed the supply voltage.
