AZV3001, AZV3002
Single/Dual Channel Low Voltage Push-Pull Output Comparators
Description
AZV3001 and AZV3002 are single and dual channel comparators
developed for new generation low-power comparator families for
battery-powered devices and systems requiring low voltage operation.
The supply current each comparator typically consumes is 6µA to
extend battery life. It is guaranteed to operate at a low voltage of 1.6V
and is fully operational up to 5.5V. These features make the AZV3001
and AZV3002 convenient for use in 1.8V, 3.0V and 5.0V systems, and
are perfectly suitable for battery-powered devices from its low-power
characteristics.

Application Information
Description
The AZV3001/2 are single and dual low-voltage, low-power comparators. These devices are designed for rail-to-rail input and output
applications. 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 a low supply voltage range of 1.6V to 5.5V.
The AZV3001 /2 series has 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 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 battery- powered applications, this characteristic
results in a substantial increase in battery life.

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 voltages 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.
