MAX78700
MAX78700 is Precision ADC manufactured by Silergy.
Multichannel, Isolated, Precision ADC
General Description
The MAX78700 is an isolated analog-to-digital converter (ADC) for use with a patible MAX78xxx energy measurement processor. The device provides current and voltage measurements to the host while the host provides control, mand, 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 ponents in the measurement subsystem.
