产品概述 返回TOP
The CXDR75139 is an isolated analog-to-digital converter (ADC) for use with a compatible energy measurement processor. The device provides current and voltage measurements to the host while the host provides control, command, and power to the CXDR75139. 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
