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 feature lower analog ON-resistance (<35Ω) and faster switch time (tON <175ns) compared to the DG211 or DG212. Charge injection has been reduced, simplifying sample and hold applications. 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” operations.
The DG411/883 series are monolithic quad SPST CMOS analog switches that replace the DG211 and DG212 devices. Each package contains four independent switches with TTL and CMOS compatible digital inputs, low ON‑resistance and fast switching times.
The devices operate over a wide voltage range (up to 44 V) and are offered in a 16‑lead CERDIP package. Typical applications include audio switching, battery‑operated systems, data acquisition, sample‑and‑hold circuits, and automatic test equipment.
