Vishay Scraps Conventional Material for its New Range of Analog Switches Bids on the Future of Analog Circuits

DG9408E and DG9409E

Vishay Intertechnology announces tweak of its several Vishay Siliconix analog switch products to boost device performance and longevity.

The company has sought to replace aging silicon technology with an advanced process that improves a range of device parameters while ensuring a useful lifetime for future. This technological shift is said to be a signal of Vishay’s perennial support for its analog switch and multiplexer product lines, which the company had pioneered in the 1960s.

The new enhanced family of analog switches and multiplexers introduced by Vishay Siliconix is designed on a high-density 18 V process.

The process not only offers an upgrade path for customers using Vishay’s current 12 V series products, but is touted to enable Vishay to develop new precision analog products with higher complexity for sensitive analog designs.

Key improvements to device specifications include:

  • Increase of the operating voltage from 12 V to 16 V.
  • Lower leakage.
  • Reduced parasitic capacitance, and faster switching speeds; and enhanced ruggedness, with higher latch-up current and ESD protection ratings.

Addressing the above given specs; the new DG9408E and DG9409E — drop-in upgrades for the popular DG9408 and DG9409  featuring 20% lower switch on-resistance, 10% faster switching speeds, 35% lower parasitic capacitance, enhanced latch-up capability to 400 mA, and guaranteed ESD protection to 2.5 kV (human body model).

Vishay claims to build the new devices on a mature process platform in an established facility with an eye towards shortening lead times and fully supporting the long life cycles of these analog switch products, which are widely used in such market applications as industrial control and automation systems, audio and video signal routing, instrumentation and test equipment, data acquisition, communication systems, and medical and healthcare systems.

The 12 V device families being upgraded to enhanced versions are summarized in the table below.

DG408L, DG409L DG408LE, DG409LE
DG411L, DG412L, DG413L DG411LE, DG412LE, DG413LE
DG441L, DG442L DG441LE, DG442LE
DG9424, DG9425, DG9426 DG9424E, DG9425E, DG9426E
DG4051, DG4052, DG4053, DG9051, DG9052, DG9053, DG9251, DG9252, DG9253 DG4051E, DG4052E, DG4053E
DG9408, DG9409 DG9408E, DG9409E
DG9454 DG9454E

Citing on the new development, Roy Shoshani, vice president, power ICs at Vishay said, “These new products are the first in a series of innovative analog devices that this new process enables. We’re confident that customers who adopt these new products will see performance improvements in their precision analog circuit designs. We know that our customers designing for applications such as industrial, instrumentation, and healthcare require long product life cycles, and this new platform will support that while providing improved performance and ruggedness. In addition, improved manufacturing will result in shorter lead times, making product more readily available.”

Availability

Samples and production quantities of the enhanced analog switch products are available now, with lead times of 10 weeks.
