The DG442DVZ is a monolithic quad SPST CMOS analog switch designed for applications requiring low ON resistance and fast switching times. It features a maximum ON resistance of 85Oc and a switching time of less than 250ns, making it suitable for high-speed signal routing. The device operates within a voltage range of up to 44V, allowing it to handle signals of up to 40VP-P. It supports both single-ended and split supply configurations, with power supply requirements ranging from +5V to +34V or ±5V to ±22V. This switch is TTL and CMOS compatible, and it has been optimized to reduce charge injection, which is beneficial for sample and hold circuits. The DG442DVZ is available in a 16-lead TSSOP package and is RoHS compliant, making it suitable for environmentally conscious designs. It is an upgrade from the older DG201A and DG202 series, providing improved performance for audio switching, data acquisition, and communication systems.
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.brbr These switches feature lower analog ON resistance (85?) and faster switch time (tsubON/sub 250ns) compared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications.brbr 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. The 44V maximum voltage range permits controlling 40VP-P signals. Power supplies may be single ended from +5V to +34V, symmetrical supplies from ±5V to ±22V or asymmetrical supplies limited to a maximum differential voltage of 44V with a V+ max of 34V or a V- max of -25V.brbr 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. The switches in the DG441 and DG442 are identical, differing only in the polarity of the selection logic.
