Monolithic, Quad SPST, CMOS Analog Switches
The DG441 and DG442 monolithic CMOS analog switches are drop-in replacements for the popular DG201A and DG202 series devices. They include four independent single pole single throw (SPST) analog switches, TTL and CMOS compatible digital inputs, and a voltage reference for logic thresholds.
These switches feature lower analog ON resistance (<85Ω) and faster switch time (tON <250ns) compared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications.
The improvements in the DG441 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies.
