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. The chip is specialized for motor-control applications. For the position sensor analysis, two up−down counters are added on the silicon. This feature ensures that the analog input of the encoder is held at the same point of time as the counter value.
