6.9.13 Comparator_A
The primary function of the comparator_A module is to support precision slope analog-to-digital
conversions, battery-voltage supervision, and monitoring of external analog signals.
6.9.14 ADC12
The ADC12 module supports fast, 12-bit analog-to-digital conversions. The module implements a 12-bit
SAR core, sample select control, reference generator and a 16 word conversion-and-control buffer. The
conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored
without any CPU intervention.
6.9.15 DAC12
The DAC12 module is a 12-bit R-ladder voltage-output DAC. The DAC12 can be used in 8-bit or 12-bit
mode and can be used in conjunction with the DMA controller. When multiple DAC12 modules are
present, they may be grouped together for synchronous operation.
6.9.16 OA
The MSP430xG461x has three 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 before analog-to-
digital conversion.
