ADG451, ADG452 ADG453 monolithic CMOS devices comprising four independently selectable switches. They designed enhanced LC2MOS process that provides power dissipation gives high switching speed resistance. resistance profile very flat over full analog input range ensuring excellent linearity distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make parts suitable video signal switching. CMOS construction ensures ultralow power dissipation making parts ideally suited portable battery powered instruments. ADG451, ADG452 ADG453 contain four independent single-pole/single-throw (SPST) switches. ADG451 ADG452 differ only that digital control logic inverted. ADG451 switches turned with logic appropriate control input, while logic high required ADG452. ADG453 switches with digital control logic similar that ADG451 while logic inverted other switches. Each switch conducts equally well both directions when input signal range which extends supplies. condition, signal levels supplies blocked. REV.

CAUTION (electrostatic discharge) sensitive device. Electrostatic charges high 4000 readily accumulate human body test equipment discharge without detection. Although ADG451/ADG452/ADG453 feature proprietary protection circuitry, permanent damage occur devices subjected high energy electrostatic discharges. Therefore, proper precautions recommended avoid performance degradation loss functionality.

switch capacitor leakage, voltage hold capacitor will decrease with time. ADG451/ ADG452/ADG453 minimizes this droop leakage specifications. droop rate further minimized polystyrene hold capacitor. droop rate circuit shown typically µV/µs. second switch, SW2, that operates parallel with SW1, included this circuit reduce pedestal error. Since both switches will same potential, they will have differential effect AD711, which will minimize charge injection effects. Pedestal error also reduced compensation network This compensation network reduces hold time glitch while optimizing acquisition time. Using illustrated amps component values, pedestal error maximum value over input range. Both acquisition settling times
