Silergy MAX71071
The MAX71071 are dual-channel isolated analog-todigital converters (ADCs) for use with a compatible host. The device provides current and voltage measurements to the host while the host provides control, command, and power to the MAX71071. These metrology ADCs operate over the industrial temperature range and come in a 10-pin μSOP package.GENERAL DESCRIPTION
A pulse transformer provides the isolated data, clock, and power path between the device and host, eliminating the need for additional isolation components in the measurement subsystem. Block Diagram Benefits andFEATURES
