The ADS7869 is a motor-control front-end that includes three analog-to-digital converters (ADCs) with a total of seven sample-and-hold capacitors and 12 fully differential input channels. There are four sign comparators connected to four input channels. There are also three additional fully differential inputs; each input is connected to a window comparator and a sign comparator.
In addition, the ADS7869 also offers a very flexible digital interface with a parallel port that can be configured to different standards. Furthermore, a serial peripheral interface (SPI) and a specialized serial interface with three data lines (VECANA01 mode) are provided. This allows the ADS7869 to interface with most digital signal processors (DSPs) or microcontrollers.
