6.5 GPAMP Design Considerations

MSPM0L devices include GPAMP (General-Purpose Amplifier) modules that can used for signal amplification with some external resistors and capacitors, as seen in #FIG_TL5_LB4_PWB.

The GPAMP can also be used as a buffer for the internal ADC. #FIG_VQB_YF3_GVB shows an example of this configuration.
