MAXQ3183 Maxim, MAXQ3183 Datasheet - Page 38

• Manufacturer Part Number: MAXQ3183
• Description: The MAXQ3183 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
with Harmonics and Tamper Detect
This register contains gain coefficient for phase X voltage channel. The raw values are taken from the selected mea-
surement quantity and scaled by the factor:
Note: Bit 15 of this register must be set to zero for correct operation.
This register contains gain coefficient for phase X energy. The raw values are taken from the selected measurement
quantity and scaled by the factor:
Note: Bit 15 of this register must be set to zero for correct operation.
This signed register contains the angle as a fraction of one radian to add to the measured phase angle when the
measured current is above the value given in I1THR. This signed value ranges from -0.5 radian (at a value of
0x8000) to +(0.5 - 2
