MILPITAS, CA--(Marketwire - May 18, 2009) - Intersil Corporation (NASDAQ: [ ISIL ]), a world leader in the design and manufacture of high-performance analog and mixed signal semiconductors, today introduced new dual 0.5 Ohm Single Pole/Single Throw and Single Pole/Double Throw switches featuring single supply, negative signal handling, and audio click and pop elimination.

The [ ISL54062 ] is a dual 0.5 Ohm SPDT switch featuring low ON-resistance and low-voltage operation, with negative signal handling on signal inputs. It operates from a single +1.8V to +6.5V supply and passes signals that swing a maximum of 6.5V below the positive supply rail. The ISL54062 and other members of the new series -- the[ ISL54063 ] and [ ISL54064 ] -- incorporate Intersil's click and pop circuitry. The[ ISL54065 ] is designed to enable users to digitally select click and pop elimination and also to open circuit all switches, if desired.

The new switches provide a low loss, low distortion capability for AC-coupled or DC-coupled bipolar signal sources using only a single positive supply rail, which eliminates the need for a negative supply. This enables the devices to pass a 2Vrms signal, standard in many consumer audio products, using only a positive 3V supply. Switching speeds of tON = 55ns, tOFF = 18ns guarantee fast 'break before make' operation. Power consumption is an ultra low 20nA; bandwidth is 35 MHz; and crosstalk is -95dB at 100 kHz. ESD protection of > 6kV on all pins assures robustness, an important feature when the devices are being used on connector interfaces. The switches also include excellent R-on flatness, to ensure minimal signal distortion. Failsafe power-off protection eliminates the risk that external sources will inadvertently turn on the switch.

The combination of industry-leading features and capabilities makes the ISL54062/63/64/65 series an ideal choice for battery-powered handheld products, consumer audio equipment and portable test/measurement and medical devices.

Pricing and Availability

The ISL54062/63/64 are available in compact, space-saving 3mm x 3mm 10-lead TDFN and 10-lead 1.8mm x 1.4mm µTQFN packages. Prices start at $0.69 each in 1,000-unit quantities. The ISL54065 comes in a 12-lead 2.2mm x 1.4mmµTQFN, with prices starting at $0.75 each in 1,000-piece units.
