DESCRIPTION  
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. 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.
