Motor Control 3-Phase Power Measurement Cellular Phones Data Acquisition
The AD7861 is a multichannel simultaneous sampling A/D Converter (ADC) configured for the acquisition of voltage inputs in a motor control solution or three-phase power system.
The AD7861 combined with Analog Devices’ 16-bit fixed-point digital signal processor (DSP) provides a low cost 16-bit fixed-point microcontroller solution. The input stage has been designed to accommodate the types of signals frequently found in motor drives. The VIN1, VIN2, and VIN3 channels are simultaneously sampled inputs suitable for stator current acquisition. The AUX0–AUX3 channels are multiplexed and are suitable for slower moving inputs such as temperature and bus voltage of the diode rectifier output in a motor control application.
