 Geneva,
October 17, 2003 - STMicroelectronics (NYSE: STM) has introduced a
pair of SPDT analog switches whose packaging and low insertion losses
make them ideal for use in consumer products including audio and video
devices, cellphones, notebook PCs, PDA and many forms of portable instrumentation.The STG3699 is a quad SPDT analog switch and the STG3684 is a dual SPDT analog switch. They include multiple "Single Pole Dual Trough" cells and can work in bi-directional mode, using 1.8V compatible digital control pins. The switches are housed in a QFN package that is just 3 x 3mm, making them useful where space is at a premium. The on-resistance of the devices is less than 0.5Ohm. This reduces distortion to a minimum in audio circuits, ensuring high-fidelity signal routing for products such as cellular phones. The low on-resistance of the parts also means low insertion losses in video applications. Switching times are less than 300ps. The on-resistance of the switches is matched to within 0.06Ohm, which is useful when switching differential signals. The parts operate at supply voltages of between 1.65V and 3.6V and are designed to support high current up to ±500mA 10% duty cycle. Power consumption is less than 200nA, making the parts suitable for use in battery-powered systems. All inputs and outputs are protected against static discharge and transient excess voltages.
