New Audio Jack Detector and Low-Voltage Analog Switch Are First in New Family of Devices to Offer Enhanced Package
Vishay Intertechnology, Inc. today introduced a new 1.4 mm by 1.8 mm miniQFN10 package with an ultra-thin 0.35 mm profile, providing a space-saving alternative to larger miniQFN10 and WCSP devices commonly used in portable applications. The new Vishay Siliconix DG2592 audio jack detector and DG2750 low-voltage dual SPDT analog switch are the first devices in a new family of solutions to feature the enhanced package.
Typical miniQFN10 and WCSP packages feature profiles of 0.55 mm. The new ultra-thin miniQFN10 package of the DG2592 and DG2750 is 36 % thinner, saving valuable PCB space and allowing for slimmer end products, including handheld healthcare instruments, smartphones, tablets, portable media players, digital cameras, and wearable Internet of Things (IoT) devices. Compared to WCSP packages, the enhanced miniQFN10 offers easier surface mounting and is better suited for the flexible PCBs commonly utilized in portable designs. The package exceeds current RoHS standards and is completely lead (Pb)-free.
The DG2592 is an audio jack detector and pop noise control switch IC that features integrated circuits for detecting the presence of a stereo headset with a microphone and send/end control button. The device features a wide operating range of 1.6 V to 5.5 V, low quiescent current of 10 μA max. at 1.8 V, and a 1.2 Ω max. MIC bias switch for quick discharge and clamping. The detector offers ESD tolerance > 8 kV (human body model).
The DG2750 is a low-on-resistance, bidirectional device that is capable of switching negative swing audio without the need for a coupling capacitor. Designed to operate from a single 1.8 V to 5.5 V power supply, the analog switch conducts audio signals in both directions with very low distortion. Built on sub-micron CMOS low-voltage process technology, the device offers a very low quiescent current and provides latch-up protection > 600 mA per JESD78.
Samples of the DG2592 and DG2750 are available now. Production quantities will be available in Q1 2016, with lead times of 13 to 14 weeks for large orders.
