MAX71020A Datasheet PDF - Silergy

●The MAX71020A is a single-chip analog front-end (AFE) for use in embedded energy measurement applications. It contains the compute engine (CE) found in Maxim Integrated’s fourth-generation meter system-on-chip (SoC) and an improved analog-to-digital converter (ADC). It interfaces to a host controller of choice over a SPI interface.

●The MAX71020A comes in a 28-pin TQFN package.
