OBSOLETE GENERALDESCRIPTION
The AD7S19 consists of four SPDT switches which steer cur-
rent to one of two buss lines that normally should be termin-
ated at ground or the virtUal ground of an operational ampli-
fier. 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 con-
verters. variable gain amplifiers. and digitally controlled sum-
