DG411/883

Description

The DG411/883 series monolithic CMOS analog switches are drop-in replacements for the popular DG211 and DG212 series devices. They include four independent single pole throw (SPST) analog switches, and TTL and CMOS compatible digital inputs. These switches DG411/883 feature lower analog ON-resistance (ON The improvements in the DG411/883 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, or split from 5V 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 15V analog input range. This permits independent control of turn-on and turn-off times for SPDT configurations, permitting break-before-make or make-before-break operation with a minimum of external logic.
