Intersil Launches Ultra Low Resistance Quad Analog Switch for Cell Phone and Handheld Consumer Electronic Products
-- Performance upgrade drop-in for the MAX4780~-- New ISL84780 combines Low Resistance with high ESD capability
MILPITAS, CA, January 18, 2005 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced the ISL84780, an ultra low sub 0.5 ohms resistance quad analog switch that offers precise switching capability from a single 1.6 V to 3.6 V supply with low distortion and high speed operation. The ISL84780 provides a performance upgrade with the industrys lowest R(ON), and better R(ON) flatness, R(ON) matching, and double the ESD withstand level of existing competing devices. This enables increased reliability and provides significant added value to customers.
A true bi-directional, quad single pole/double throw (SPDT) analog switch with a typical resistance of less than 0.5 ohms over the full input signal range, the ISL84780 operates from a nominal single 3.3 V supply and is available in TSSOP and small TQFN packaging for space-constrained applications such as portable battery powered consumer electronic products and cell phones. The device is built in an advanced sub-micron CMOS process and has at least 6 kV of ESD resistance, making it capable of withstanding the abuses of everyday cell phone use.
The device is especially well suited for portable battery-powered equipment due to its low operating supply voltage (1.6 V), low power consumption (5.4 uW Max), low leakage currents (30 nA max), and the tiny TQFN and TSSOP packages. The ultra low on-resistance and typical R(ON) flatness of 0.05 ohms, result in total harmonic distortion (THD) of better than 0.002% into a 32 ohms headphone load, making the ISL84780 ideal for use in low distortion audio paths such as in MP3 players, cell phones and CD audio devices.
