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.
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 1.4mm µTQFN,
with prices starting at $0.75 each in 1,000-piece units.
