Analog-to-Digital Converter (ADC)
This ADC is applicable for the ADC found on the TMS320x2833x family of processors. This includes all
Flash-based, ROM-based and RAM-based devices within the 2833x family.
The TMS320x2833x ADC module is a 12-bit pipelined analog-to-digital converter (ADC). The analog
circuits of this converter, referred to as the core in this document, include the front-end analog multiplexers
(MUXs), sample-and-hold (S/H) circuits, the conversion core, voltage regulators, and other analog
supporting circuits. Digital circuits, referred to as the wrapper in this document, include programmable
conversion sequencer, result registers, interface to analog circuits, interface to device peripheral bus, and
interface to other on-chip modules.
