DG445DYZ

The DG445DYZ is a single-pole single-throw (SPST) monolithic quad CMOS Analog Switch drop-in replacements for the popular DG211 and DG212 series devices. It includes four independent single-pole single-throw (SPST) analog switches and TTL and CMOS compatible digital inputs. This switch features lower analog ON resistance (85O) and faster switch time (tON 250ns) compared to the DG211 and DG212 charge injection has been reduced, simplifying sample and hold applications. The improvements in this switch series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling ±20V signals when operating with ±20V power supplies. The four switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a ±5V analog input range.
