Intersil Releases Industry-leading Sub-0.5-Ohm Low-voltage Dual Analog Switch Targeted for Portable Equipment and Handheld Applications

-- New switch offers industry’s lowest R(ON) and R(ON) flatness with the highest ESD withstand rating, very low power consumption and ultra-fast switching

MILPITAS, CA, July 12, 2004 – Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced a new high-performance dual switch that provides enhanced performance and reliability to replace currently available devices. The MightyMUX™ ISL84684 is a true bi-directional, ultra-low resistance, low-voltage, dual single-pole double throw (SPDT X 2) analog signal switch intended for use in cellphones, smartphones, PDAs and other portable battery-powered products. The ISL84684 has two independent switches, allowing it to replace two discrete SPDT devices where space is critical.

“Customers using competing switches can upgrade circuit performance by replacing them with Intersil’s new ISL84684, which is pin-compatible with some existing switches. The ISL84684 provides lower R(ON), and better R(ON) flatness and R(ON) matching than existing competing devices. It offers significantly lower R(ON) at lower supply voltages, such as 1.8 V,” said Mamoon Rashid, director of marketing for Intersil’s Analog Solutions Products Group. “What’s more, with a greater than 9 kV ESD withstand rating, this dual switch offers the industry’s highest ESD withstand level of all competing sub-1-Ohm devices, which yields increased reliability in handheld use and significant added value to our customers.”

The ISL84684 is a guaranteed break-before-make dual single-pole double-throw (SPDT) switch IC that operates over a 1.65- to 3.6-V supply range, making it ideally suited for Alkaline, Nickel-Metal Hydride as well as Lithium-ion and Lithium Polymer battery-powered applications. The R(ON) conduction resistance of each switch is a very low 0.29 Ohms at 2.7 V and only 0.4 Ohms at 1.8 V, which reduces signal loss to improve audio output levels in battery powered handheld products. When operated from a 2.7-V supply, the ISL84684 switches have a typical R(ON) flatness and channel matching of 0.03 Ohms, making them ideal for use in low distortion audio paths such as MP3 players in Cell-Phones, and CD audio devices.

When operated from a nominal 3-V supply, the devices are 1.8-V logic compatible. Switching speed at a supply of 2.7 V is typically a very fast 14-ns turn-on and 6-ns turn-off, reducing switching noise. This is particularly important in headphone audio switching applications.
