LC7972VA
Overview
The LC7972VA and LC7972VB are dual inverting/noninverting operational amplifier ICs that are fabricated in a CMOS process. These ICs provide a programmable offset correction function and a power saving function for use when the operational amplifier is unused, both of which can be controlled from a microprocessor interface.
- The following modes are supported. These are selected via port level settings.
