Low power 12-V triple SPDT switch is optimized for 3D shutter glasses
March 14, 2011 // Paul Buckley
Vishay Intertechnology, Inc., has released a new compact triple SPDT (triple 2:1) switch optimized for 3D shutter glasses. The DG9454 guarantees 1.8 V logic compatibility over an operational voltage range from 2.7 V to 13.2 V at V+ and 2.5 V to + 5.5 at VL, and features low power consumption down to < 1 µA to greatly enhance battery life.
Available in the ultra-compact 1.8 mm x 2.6 mm miniQFN-16 package, the device enables smaller and lighter 3D goggles for end users.
The new generation of 3D shutter glasses will continue to incorporate lower MCU voltage designs. The new DG9454 is ready to meet this demand by guaranteeing <1.8V logic compatibility while maintaining low power consumption. By providing consumption of < 1 µA at V+ and 3 µA to 5 µA at VL without the need for an extra logic translation circuit, the device reduces the component count, lowering costs and providing further space savings.
The DG9454 offers high bandwidth to 540 MHz, low charge injection over the full signal range of < 0.9 pQ, low switch capacitance of 2 pF typical, and isolation and crosstalk performance of - 65 dB at 10 MHz and < -90 dB at 100 KHz. The specifications make the device a high-performance switch for data acquisition applications, as well as healthcare and control and automation equipment.
Processed with advanced CMOS technology, the DG9454 conducts equally well in both directions, and offers rail to rail analog signal handling. The device offers an operating temperature from - 40 to + 125 °C.
Vishay Siliconix manufactures the DG9454 with lead (Pb)-free terminations. The miniQFN-16 package features nickel-palladium-gold terminations that meet all JEDEC standards for reflow and MSL ratings. The switch is compliant to RoHS Directive 2002/95/EC and halogen-free according to the IEC 61249-2-21 definition.
Samples and production quantities of the DG9454 are available now, with lead times of eight weeks for standard orders.
