Notes: 19. Pulse output timing is specified at DCLK = 4.096 MHz, E2MODE = 0, and E3MODE[1:0] = 0. Refer to
6.7 Energy Pulse Outputs on page 20 for more information on pulse output pins.
20. Timing is proportional to the frequency of DCLK.

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