This release in:

MALVERN, Pa. — Jan. 27, 2015 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced three new 200 Ω precision monolithic quad single-pole single-throw (SPST) analog switches in the ultra-compact WCSP 4 bump by 4 bump array package. The smallest such devices in the industry, the Vishay Siliconix DG2501, DG2502, and DG2503 save space in wearable electronics and sensors and consumer and communication devices, while offering high precision characterized by low parasitic capacitance, charge injection, and leakage current.

Measuring 1.4 mm by 1.4 mm with a 0.35 mm pitch and top-side lamination for increased ruggedness, the switches released today are 50 % smaller than the closest competing device and 95 % smaller than switches in the standard QFN16 package. Combining their compact size with typical power consumption of < 0.01 μW to prolong battery life, the DG2501, DG2502, and DG2503 are ideal for analog front-end signal switching, programmable gain control and sample and hold circuits, and multiple analog input multiplexing in smart watches, medical patches, fitness monitors, sensors, and other such products that make up the Internet of Things (IoT).

The switches provide low CD(OFF) of 2.6 pF, CD(ON) of 7.6 pF, charge injection down to −0.7 pC, and typical switch-on leakage current of 9 pA. The DG2501, DG2502, and DG2503 offer high ESD tolerance > 8 kV (human body model) and latch up current > 800 mA per JESD78. Each switch conducts equally well in both directions when on and supports analog signals up to the supply voltage.

The DG2501, DG2502, and DG2503 each feature four independently selectable SPST switches with closely matched channel resistance. The DG2501 is normally closed, while the DG2502 is normally open. The DG2503 has two normally open and two normally closed switches. All three devices feature guaranteed break-before-make operation for use in multiplexer applications. The switches operate from a single 1.8 V to 5.5 V power supply and offer logic thresholds of 1.4 V and 1.8 V at 3 V and 5 V inputs, respectively, to ensure low-voltage TTL/CMOS compatibility. The Vishay GREEN devices are RoHS-compliant and halogen-free.

Samples and production quantities of the DG2501, DG2502, and DG2503 are available now, with lead times of 10 weeks for large orders.
