MAX71020AETI+

Overview

The MAX71020AETI+ is a single-phase programmable Analog Front End (AFE) manufactured by Silergy, part of the Maxim Integrated portfolio. It features a 3.3V supply voltage and integrates one voltage input channel and one current input channel for signal acquisition. The device includes an on-chip temperature sensor and supports both internal and external oscillator configurations. Communication with the host system is handled via a Serial Peripheral Interface (SPI). Memory resources consist of One-Time Programmable (OTP) Flash and 1 KByte of internal RAM. The component is available in TQFN-28 and TSSOP-28 packages.

Feature Summary

• Integrates analog front-end circuitry for single-phase energy measurement applications
• Includes a dedicated signal processing core for data handling
• Features built-in temperature sensing capabilities
• Supports flexible clocking through internal or external oscillator options

Applications

• Single-phase energy metering systems
• Programmable power monitoring devices
• Utility metering infrastructure testing equipment

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is listed under Silergy in distributor catalogs despite the Maxim Integrated branding context. Confirm package availability matches your design requirements, as the component is offered in both TQFN-28 and TSSOP-28 formats. Ensure the ordering suffix corresponds to the desired package type and lead time constraints before finalizing procurement.

Selection Notes

Select this component when designing single-phase AFE solutions requiring integrated signal conditioning and processing. The choice depends on the need for a 3.3V operating voltage and SPI connectivity. Consider the memory configuration if firmware storage is required on-chip. Evaluate the package size constraints against the available TQFN-28 or TSSOP-28 options to ensure compatibility with the PCB layout.

Part Context

This device belongs to the family of high-accuracy Analog Front Ends designed for utility metering. It serves as a specialized interface between analog sensors and digital processing units. The product line focuses on providing precise measurement capabilities for electrical parameters in single-phase environments, supporting both standalone and embedded system architectures.
