Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended.

4. Guaranteed by design and/or testing of related parameters. Not 100% tested in production.

5. The MIC3000 will attempt to enter its shutdown state when VDD falls below VUVLO. This operation requires time to complete. If the supply voltage falls

too rapidly, the operation may not be completed.

6. Does not include quantization error.

7. Final test on outgoing product is performed at TA = +25°C.

8. The MIC3000 will not respond to serial bus transactions during an EEPROM write-cycle. The host will receive a NACK during tWR.
