The Analog Devices DG403 is an improved, dual high-speed SPDT (single-pole double-throw) CMOS analog switch designed for precision, high-performance switching of analog signals, with a maximum signal voltage range of 44V permitting control of 30Vp-p signals, guaranteed on-resistance matching of 2 ohm max between switches, and guaranteed on-resistance flatness of 3 ohm max over the signal range, housed in a 16-pin SOIC package. An analog switch is a semiconductor device that passes or blocks analog signals under digital control, acting as the solid-state equivalent of a relay contact. Within the signal-chain hierarchy, the DG403 belongs to the analog switches and multiplexers family, positioned below analog multiplexers (which route many channels) and above simple pass elements, and it is a core building block of analog front-end and signal-routing subsystems in data acquisition systems. Key features include CMOS or TTL-level compatible logic activation, operation from single-ended supplies of +5V to +34V or split supplies from plus/minus 5V to plus/minus 17V, and a high-voltage silicon-gate process. Each of the two independent control inputs selects between two signal paths, providing the equivalent of two SPDT relay contacts with no moving parts. The improved redesign (originally by Maxim Integrated, now Analog Devices) added guaranteed low on-resistance matching between switches and flatness over the signal range, while the epitaxial layer prevents the latch-up associated with older CMOS technologies. The ON-resistance variation with analog signal level is quite low over a plus/minus 15V analog input range, ensuring low signal distortion. Typical applications include audio and video signal routing, precision data-acquisition channel selection, sample-and-hold circuits, and replacing electromechanical relays in industrial and instrumentation signal paths. Where two single-pole single-throw contacts are needed, the DG401 offers SPST functionality; the DG405 offers DPST. Designers should observe supply-rail headroom: analog signal swings must remain within the supply rails, and logic inputs must meet CMOS/TTL threshold levels for correct switching.

It contains four independent single-pole single-throw switches with TTL and CMOS compatible logic inputs and an internal voltage reference for logic thresholds. An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control, sitting within the broader hierarchy of signal-switching devices: analog switch, multiplexer/demultiplexer family, and interface ICs. Quad SPST switches are favored where independent, per-channel on/off control of four signal lines is needed without combining channels into a common bus, as a conventional multiplexer would require. Key features of the DG441DJZ include four independently addressable normally-closed switches, 85 ohm guaranteed maximum on-resistance, TTL and CMOS logic compatibility across the full supply range, and drop-in compatibility with the popular DG201A and DG202 series devices. The DJZ suffix denotes the industrial temperature grade in a 16-pin plastic DIP package, supporting through-hole assembly for industrial and instrumentation designs. Architecturally, the DG441 family uses monolithic CMOS construction that conducts equally well in either signal direction, allowing bidirectional signal flow.
