The DG412/883 CMOS analog switch is a drop-in replacement for the popular DG212 device. It includes four independent single pole single throw (SPST) analog switches and has TTL/CMOS compatible digital inputs.
The DG412-13/883 analog switches feature lower analog ON-resistance (<35Ω) and faster switch time (tON <175ns) compared to the DG212. Charge injection has been reduced, simplifying sample and hold applications.
The improvements in the DG412-13/883 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. All switches in the DG412/883 use positive logic (i.e. a logic "1" turns the switch ON). Two of the switches (1 and 4) in the DG413/883 use positive logic and the other two switches (2 and 3) use negative logic (i.e. a logic "1" turns the switch OFF). This permits independent control of turn-on and turn-off times for SPDT configurations, permitting "break-beforemake" or "make-before-break" operation with a minimum of external logic.
