New audio jack detectors and low voltage analog switches are the first products in the family to feature enhanced packaging Vishay Intertechnology, Inc. introduced the audio via detector DG2592 and the low voltage dual SPDT analog switch DG2750 in an ultra-thin 1.4mm x 1.8mm miniQFN10 package with a thickness of 0.35mm to replace the larger miniQFN10 commonly used in portable applications. WCSP devices achieve space saving. The new Vishay Siliconix DG2592 Audio Hole Detector and DG2750 Low Voltage Dual SPDT Analog Switch are the first devices in a new family of reinforced packages. Usb C Cable is also known as Usb Cable Type C interface,is an interface specification consisting of a Type-C plug and a type-C socket.Its highlights are thinner design,faster transmission speed (up to 10Gbps),stronger power transmission (up to 100W).In addition, USB-C interface also supports double-sided insertion,front and back can be inserted at will, compared with USB2.0/USB3.0 more advanced.Usb-c has been given better media properties,faster transfer speeds,and better compatibility with charging.The new generation USB-C has faster transmission speed than USB,stronger power transmission, smaller interface size,and supports bidirectional transmission with stronger compatibility.
Thinner bodies require thinner ports,which is one of the reasons USB-C is here to stay.The USB-C port is 0.83 cm long and 0.26 cm wide.The old USB port measuring 1.4cm long and 0.65cm wide looks outdated.This also means that the end of USB Cable will be one-third the size of the plug of A standard USB-A cable.The USB-C port is the same on the front and back.This means that no matter how you insert the port,it will be correct.Users do not have to worry about the pros and cons of traditional USB ports.

The typical miniQFN10 and WCSP are 0.55mm high, while the DG2592 and DG2750 ultra-thin miniQFN10 packages are 36% thinner than the first two packages, saving valuable PCB space and allowing designers to design thinner end products, including handheld Healthcare instruments, smartphones, tablets, portable media players, digital cameras, and wearable Internet of Things (IoT) devices. Compared to the WCSP package, the enhanced miniQFN10 is easier to surface mount and is more suitable for flexible PCB boards commonly used in portable products. This package is environmentally superior to current RoHS standards and is completely lead-free.
The DG2592 is an audio jack detector and plosive control switch chip with an integrated circuit that detects the presence of stereo headphones with a microphone and SEND/END control buttons. The device operates from 1.6V to 5.5V, with a maximum quiescent current of 10μA and a maximum resistance of 1.2Ω at 1.8V. The MIC bias switch quickly discharges and clamps. The detector's ESD resistance reaches 8kV (human body model).
The DG2750 is a low-resistance bidirectional device that switches the negative swing audio signal without the need for a coupling capacitor. The analog switch operates from a 1.8V to 5.5V power supply and delivers audio signals with very low distortion in both directions. The device is fabricated in sub-micron CMOS low-voltage process technology with very low quiescent current and latch-up protection greater than 600mA to meet per JESD78 requirements.
Samples of the DG2592 and DG2750 are available now, with volume production scheduled for the first quarter of 2016, with lead times of 13 to 14 weeks for larger orders.
