MSP430FG42x0
MIXED SIGNAL MICROCONTROLLER
SLAS556A − JULY 2007 − REVISED AUGUST 2007
15
POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
operational amplifier (OA)
The MSP430FG42x0 has two configurable low-current general-purpose operational amplifiers. Each OA input
and output terminal is software-selectable and offers a flexible choice of connections for various applications.
The OAs primarily support front-end analog signal conditioning prior to analog-to-digital conversion.
