DG442DYZ

The DG442DYZ is a single-pole single-throw (SPST) monolithic quad CMOS Analog Switch drop-in replacements for the popular DG201A and DG202 series devices. It includes four independent single-pole single-throw (SPST) analog switches, TTL and CMOS compatible digital inputs and a voltage reference for logic thresholds. This switch features lower analog ON resistance (250ns) compared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications. The improvements in this series switch 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 40VP-P signals. Power supplies may be single ended from 5 to 34V, or split from ±5 to ±20V. 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.
