DESCRIPTION
The IVA-14 series MMlCs are variable gain amplifiers. The IVA-14208 is housed in a miniature low cost plastic surface mount package. The IVA-14228 is housed in a miniature hermetic ceramic surface mount package. Both devices can be used in any combination of single-ended or differential inputs or outputs (see Functional Block Diagram). The lowest frequency of operation is limited only by the values of user selected blocking and bypass capacitors.
