MAX78700 Multichannel, Isolated, Precision ADC General Description The MAX78700 is an isolated analog-to-digital converter (ADC) for use with a compatible MAX78xxx energy measurement processor. The device provides current and voltage measurements to the host while the host provides control, command, and power to the MAX78700. A pulse transformer provides the isolated data and power path between the device and host, eliminating the need for additional isolation components in the measurement subsystem. Benefits and Features ● Better Than 0.5% Watt-Hour Accuracy Over Wide Dynamic Range Using a Single Calibration Point High-Resolution Delta-Sigma ADC Factory-Trimmed Voltage Reference and Die Temperature Sensor ● Simplified System Architecture No Power Supply Required Fully Powered by the Host with the Isolation Transformer Eliminates Data Isolation Components Reduced Form Factor and Bill of Materials ● Small 10-Pin μMAX Package Ordering Information appears at end of data sheet.
