SD16_A
The SD16_A module supports 16-bit analog-to-digital conversions. The module implements a 16-bit
sigma-delta core and a reference generator. In addition to external analog inputs, an internal V
CC
sense and
temperature s ensor are also available.
DAC12
The DAC12 module is a 12-bit R-ladder voltage-output DAC. The DAC12 may be used in 8-bit or 12-bit mode.
When multiple DAC12 modules are present, they may be grouped together for synchronous operation.
OA
The MSP430FG47x has two configurable low-current general-purpose operational amplifiers. Each OA input
and output terminal is software-selectable and offer a flexible choice of connections for various applications.
The OA op amps primarily support front-end analog signal conditioning prior to analog-to-digital conversion.
