DESCRIPTION
These devices are designed specifically for electronic assemblies requiring low profile
package types. The OMA541SF/SA is a monolithic operational amplifier capable of
operating from power supplies up to ±40V and continuous currents of up to 2 amps.
The packaging provides the ultimate in size, thermal performance and ease of
assembly. It is ideally suited for high density electronic assemblies.
