GENERAL DESCRIPTION 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 fixedpoint digital signal processor (DSP) provides a low cost 16-bit
fixed-point microcontroller solution. …
