DESCRIPTION
These devices are designed specifically for electronic assemblies requiring low profile
package types. The OMA541SF is a monolithic operational amplifier capable of
operating from power supplies up to ±40V and peak 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 and is approved to DESC
drawing 5962-94520.
