The ADC module is a successive approximation (SAR) style ADC with a selectable resolution of either 16 bits or 12 bits. The ADC is composed of a core and a wrapper. The core is composed of the analog circuits, which include the channel select MUX, the sample-and-hold (S/H) circuit, the successive approximation circuits, voltage reference circuits, and other analog support circuits. The wrapper is composed of the digital circuits that configure and control the ADC. These circuits include the logic for programmable conversions, result registers, interfaces to analog circuits, interfaces to the peripheral buses, post-processing circuits, and interfaces to other on-chip modules.
Each ADC module consists of a single sample-and-hold (S/H) circuit. The ADC module is designed to be duplicated multiple times on the same chip, allowing simultaneous sampling or independent operation of multiple ADCs. The ADC wrapper is start-of-conversion (SOC) based (see the SOC Principle of Operation section of the Analog-to-Digital Converter (ADC) chapter in the TMS320F2838x Real-Time Microcontrollers Technical Reference Manual).
Each ADC has the following features:
Not every channel may be pinned out from all ADCs. See Section 6 to determine which channels are available.
