Notes: 18. Pulse output timing is specified at MCLK = 4.096 MHz, E2MODE = 0 and E3MODE1:0 = 0. Refer to
Section 5.5 Energy Pulse Output on page 17 for more information on pulse output pins.
19. Timing is proportional to the frequency of MCLK.

Notes: 20. VA+ and AGND must satisfy [(VA+) - (AGND)] ≤ + 6.0 V.
21. VD+ and AGND must satisfy [(VD+) - (AGND)] ≤ + 6.0 V.
22. Applies to all pins including continuous over-voltage conditions at the analog input pins.
23. Transient current of up to 100 mA will not cause SCR latch-up.
24. Maximum DC input current for a power supply pin is ±50 mA.
25. Total power dissipation, including all input currents and output currents.
