ADC10
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion
result handling allowing ADC samples to be converted and stored without any CPU intervention.
operational amplifier OA (MSP430x22x4 only)
The MSP430x22x4 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.
