Features and Benefits
- On-board ADCMP380-2 comparator with configurable hysteresis and an internal reference of 0.5 V with ±2.2% accuracy
- Separate voltage supply and input pin (INPUT) for low voltage monitoring
- Enable pin (EN) for input condition override
- Built in LED for output monitoring
The ADCMP380-EVALZ evaluates the ADCMP380-2 ultralow power voltage comparator that has a 0.5 V internal reference with ±2.2% accuracy. The internal precision reference and the low input leakage current of the ADCMP380-2 allows the user to monitor the voltage of interest accurately through circuit resistors (R1, R2, and R4). These resistors can be configured to add a desired hysteresis to the input and prevent oscillations at the output.
A separate supply for the ADCMP380-EVALZ INPUT pin can be used to achieve low voltage monitoring. The user can also place an external jumper on the ADCMP380-EVALZ VCC_SEL pin to combine the voltage supply of the VCC pin and the monitoring INPUT pin on the ADCMP380-EVALZ.
The ADCMP380-EVALZ has an OUT pin that can be held low regardless of the ADCMP380-EVALZ INPUT pin state when an external jumper is placed on the ADCMP380-EVALZ EN pin, which shorts the EN pin to ground. A built in light emitting diode (LED) is placed at the ADCMP380-EVALZ OUT pin to monitor the pin status depending on the ADCMP380-EVALZ INPUT pin configuration.
The user can replace the on-board comparator with the ADCMP380-1 to have an internal reference of 1 V that is accurate up to ±1.6 %. The examples in this user guide only evaluate the ADCMP380-2. The level of monitored input and output voltages differ when using the ADCMP380-1 model.
For full details on the ADCMP380-2 and ADCMP380-1, see the ADCMP380 data sheet, which must be consulted in conjunction with this user guide when using the ADCMP380-EVALZ.
