MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 80

• Manufacturer Part Number: MAXQ3180
• Description: The MAXQ3180 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality parameters of a polyphase load
• Manufacturer: Maxim

Low-Power, Multifunction, Polyphase AFE
This register determines whether the all other measured values in the electricity meter are averaged over time. If the
value of this register is nonzero, all measured meter values are averaged using the following formula:
If the value of this register is zero, no averaging is performed. The MSB of this register must be zero.
This register specifies the b
The MSB of this register must be zero.
