MAX71071

MAX71071 Dual-Channel Isolated Metrology ADCs General Description 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. 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. These metrology ADCs operate over the industrial temperature range and come in a 10-pin μSOP package.
