General Description

The MAXQ3180 is a dedicated electricity measurement

front-end that collects and calculates polyphase volt-

age, current, power, energy, and many other metering

and power-quality parameters of a polyphase load. The

computed results can be retrieved by an external mas-

ter through the on-chip serial peripheral interface

(SPI™) bus. This bus is also used by the external mas-

ter to configure the operation of the MAXQ3180 and

monitor the status of operations.

The MAXQ3180 performs voltage and current measure-

ments using an integrated ADC that can measure up to

seven external differential signal pairs. An eighth differ-

ential signal pair is used to measure the die tempera-

ture. An internal amplifier automatically adjusts the

current channel gain to compensate for low-current

channel-signal levels.
