Original Press Release:

Vishay Intertechnology's First AEC-Q100 Qualified Analog Switch Improves Signal Integrity and Bandwidth for Automotive Applications

Designed for -40 °C to +125 °C Operation, Device Features Low and Flat Resistance of 0.37 Ω and High 338 MHz Bandwidth in Compact miniQFN16 Package

Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new AEC-Q100 (Grade 1) qualified dual DPDT / quad SPDT analog switch featuring low resistance of 0.37 Ω at 2.7 V and 338 MHz bandwidth in the compact 2.6 mm by 1.8 mm by 0.55 mm miniQFN16 package. Ideal for both analog and digital signal switching in space-constrained automotive applications, the Vishay Siliconix DGQ2788A offers ultra flat resistance and parasitic capacitance to improve signal integrity and deliver higher bandwidth.

The device released today is the first in Vishay's upcoming automotive series of analog switches designed to address signal switching requirements in the rapidly growing automotive segments of telematics, infotainment, advanced driver assistance systems (ADAS), advanced diagnostics and engine control modules, traction and stability control modules, and power windows, locks, and mirrors. These applications require audio, video, bus, and communication interface switching to bridge and route signals.

While competing devices with similar resistance can only operate up to 4.3 V, the DGQ2788A offers an extended voltage range of 5.5 V to accommodate common 5 V industrial designs. It features 10 mΩ resistance flatness compared to the competition's 500 mΩ, which results in THD of -100 dB — a 20 dB improvement. In addition, the DGQ2788A's parasitic capacitance CON of 26 pF and COFF of 14.5 pF are 70 % lower, resulting in an over 3x higher -3 dB bandwidth of 338 MHz. Competing devices with optimized bandwidth can only operate in a narrow power range of 2.3 V to 3.6 V. The DGQ2788A's switch gate controlled design provides an 88 % lower switch RC matrix. The device's wide operating voltage range, low resistance, and high bandwidth make it ideal for a variety of design needs, simplifying the BOM.

With an operating temperature range of -40 °C to +125 °C, the DGQ2788A features four independently selectable SPDT switches and two control inputs. All switches conduct equally well in both directions and can be used as multiplexers and de-multiplexers. The switch operates over a single 1.8 V to 5.5 V power supply, while its digital inputs have a 1.2 V logic threshold to ensure low voltage TTL/CMOS compatibility. The RoHS-compliant device offers break before make switching and power down protection, ESD tolerance > 2 kV (human body model), and latch up current of 300 mA per JESD78.

Samples and production quantities of the DGQ2788A are available now, with lead times of eight weeks for large orders. Pricing for U.S. delivery only starts at $0.46 in 10,000-piece quantities.
