New Low-Voltage, Dual 0.5 Ohm Switches from Intersil Eliminate the Need for Negative Supply, Provide Industry's Widest Signal Range, Highest ESD Protection and "Click-and-Pop" Circuitry
ISL54062/63/64/65 in Compact Packages are Ideal Design Choices for Handhelds and Consumer Audio Equipment
MILPITAS, CA, May 18, 2009 – Intersil Corporation (NASDAQ Global Select: 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.
