Low-Power, Active Energy, Polyphase AFE

______________________________________________________________________________________

Linearity Offset, Low Range, Phase X = A/B/C (X.OFFS_LO) (A: 0x13C, B: 0x228, C: 0x314)

This signed register contains the linearity offset for phase X current channel when the programmable gain amplifier

is set to gain of 32 (that is, the measured current is below the low current threshold). The signed value represented

by this register is added to the current value. The total linearity compensation is applied as follows:

if LINFRM = 0: X.GAIN_LO/214 x

if LINFRM = 1: X.GAIN_LO/214 x (X.IRMS + X.OFFS_LO)

Measurements—RAM Registers

On-Demand RMS Result (N.IRMS) (0x11C)

This register contains the result of the RMS calculation on the AUX channel. Usually, this is the neutral current

channel.
