Vishay Intertechnology announce three new ± 15 V precision monolithic quad single-pole single-throw CMOS analog switches built on a new CMOS process. Offering low on-resistance of 1.5 Ω, the Vishay Siliconix DG1411, DG1412, and DG1413 provide over 50% lower source parasitic capacitance in the off state and up to 80% lower charge injection compared to previous generation and competing analog switches with similar on-resistance in the same footprint.

Featuring fast 100 ns switching times, the DG1411, DG1412, and DG1413 switches are ideal for signal switching and relay replacement in data acquisition, industrial control and automation, communication, and A/V systems, as well as medical instrumentation and automated test equipment.

The new GD141x devices feature a new CMOS platform which ensures low and flat switch resistance over the full analog signal range. This new platform also offers excellent linearity, making the devices ideal for low-distortion applications, such as sample and hold circuits, programmable gain control circuits, and A/V signal routing. Low on-resistance makes them the preferred solution over mechanical relays in automatic test equipment and applications where current switching is required.

The DG1411, DG1412, and DG1413 feature four independently selectable SPST switches: the DG1411 is normally closed; the DG1412 is normally open; the DG1413 has two normally open and two normally closed switches with guaranteed break-before-make operation.

Operating from either a single 4.5 V to 24 V power supply or from dual ± 4.5 V to ± 15 V power supplies, the new analog switches don't require a VL logic supply. All digital inputs have 0.8 V and 2 V logic thresholds to ensure low-voltage TTL/CMOS compatibility.

The devices offer a maximum on-resistance flatness of 0.48 Ω, CS(OFF) of 11 pF, CD(ON) of 87 pF, and charge injection from -60 pC to +135 pC over the signal range. The DG1411, DG1412, and DG1413 are bidirectional and support analog signals up to the supply voltage when on, and block them when off. The switches are available in RoHS-compliant, halogen-free TSSOP16 and QFN16 4 mm by 4 mm packages. Samples and production quantities are available now, with lead times of eight weeks for larger orders.
