Vishay Intertechnology’s First AEC-Q100 Qualified Analog Switch Improves Signal Integrity and Bandwidth for Automotive Appl...
November 29 2017 - 11:00AM
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.
