Instructions for Use:

1. Power Supply Connection:

   • Connect the supply voltage (VCC) between 2.7V and 5.5V to the VCC pin.
   • Ensure a stable power supply to avoid fluctuations that can affect performance.

2. Input Signal:

   • The input signal should be within the range of -0.3V to VCC + 0.3V relative to AGND.
   • Avoid exceeding these limits to prevent damage to the device.

3. Output Signal:

   • The output signal will operate within -0.3V to VCC - 1.0V relative to AGND.
   • Ensure downstream components can handle this voltage range.

4. Power Consumption:

   • The typical current consumption is 40μA under normal operating conditions.
   • Design your power supply to accommodate this current draw.

5. Maximum Output Current:

   • The maximum output current is limited to 10mA due to short-circuit protection.
   • Do not exceed this limit to avoid damaging the device.

6. Reference Voltage:

   • The internal reference voltage is typically between 1.22V and 1.28V.
   • Use this value as a reference for setting up comparators or other circuits.

7. Comparator Offset Voltage:

   • At room temperature (25°C), the offset voltage is typically within ±2mV.
   • This parameter affects the accuracy of the comparator function.

8. Propagation Delay:

   • The propagation delay for a rising edge is approximately 100ns at 25°C.
   • Account for this delay in timing-sensitive applications.

Ensure all connections are secure and double-check polarity before powering the circuit. Follow good PCB layout practices to minimize noise and ensure reliable operation.
