Low-Voltage Dual SPST Analog Switch
DESCRIPTION The DG9432, DG9433, DG9434 is a dual single-pole/singlethrow monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed (tON: 25 ns, tOFF: 20 ns), the DG9432, DG9433, DG9434 is ideal for portable and battery powered applications requiring high performance and efficient use of board space.
The DG9432, DG9433, DG9434 is built on Vishay Siliconix’s low voltage BCD-15 process. An epitaxial layer prevents latchup. Break-before-make is guaranteed for DG9432, DG9433, DG9434.
Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
FEATURES • Wide operation voltage (+ 2.7 V to + 12 V) • Low charge injection - QINJ: 1 pC • Low power consumption • TTL/CMOS logic compatible over the full
operating voltage range • Available in MSOP-8 and SOT23-8 • Compliant to RoHS Directive 2002/95/EC
BENEFITS • Reduced power consumption • Simple logic interface • High accuracy • Reduce board space
APPLICATIONS • Battery operated systems • Portable test equipment • Sample and hold circuits • Cellular phones • Communication systems • Military radio • PBX, PABX guidance and control systems
