The DG444 and DG445 monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices. They include four independent single pole single throw (SPST) analog switches and TTL and CMOS compatible digital inputs.
●These switches feature lower analog ON resistance (<85Ω) and faster switch time (tON <250ns) compared to the DG211 and DG212. Charge injection has been reduced, simplifying sample and hold applications.
