Analogue switches offer upgrade path to12V products
To boost performance and longevity, Vishay Intertechnology has upgraded Vishay Siliconix analogue switches and multiplexers, replacing silicon with an advanced process that improves a range of device parameters.
They are designed on a high-density 18V process which offers an upgrade path for customers using current 12V series products, but also enables the company to develop new precision analogue products with higher complexity for sensitive analogue designs.
Key improvements to device specifications include an increase of the operating voltage from 12 to 16V; lower leakage, reduced parasitic capacitance, and faster switching speeds; and enhanced ruggedness, with higher latch-up current and ESD protection ratings. For example, the DG9408E and DG9409E (drop-in upgrades for the DG9408 and DG9409) feature 20 per cent lower switch on-resistance, 10 per cent faster switching speeds, 35 per cent lower parasitic capacitance, enhanced latch-up capability to 400mA, and guaranteed ESD protection to 2.5kV (human body model).
The analogue switch range can be used in industrial control and automation systems, audio and video signal routing, instrumentation and test equipment, data acquisition, communication systems, and medical and healthcare systems.
New part numbers are denoted with an E suffix, for example, DG411LE replaces DG411L.
Samples and production quantities are available now, with lead times of 10 weeks.
