GENERALDESCRIPTION
The AD7S19 consists of four SPDT switches which steer current to one of two buss lines that normally should be terminated at ground or the virtUal ground of an operational amplifier. It operates from a single +7.S to +10V supply with a
quiescent power dissipation of only 8.0IlW.
Typical AD7S19 applications include fast settling DIA converters. variable gain amplifiers. and digitally controlled summing amplifiers.
