DG2522 Vishay Siliconix Low Voltage, Fault Protection, SP3T Analog Switch (3:1 Multiplexer/Demultiplexer) DESCRIPTION FEATURES The DG2522 is a low on-resistance SP3T analog switch design to operation from 1.6 V to 5.5 V. The DG2522 switches signals in either direction with amplitudes up to V+. Protection circuit is built in to isolate the signals if any of them swings above V+. It guaranteed low leakage level for isolation in power down mode. Built on Vishay Siliconix’s sub-micro CMOS technology, the DG2522 achieves switch on-resistance of 0.8 Ω at 4.5 V V+ with 0.6 Ω flatness. It has superior 0.008 % THD (total harmonic distortion) over frequency of 20 Hz to 20 kHz. It provides - 59 dB off-Isolation, - 65 dB crosstalk at 1 MHz, and 105 MHz - 3 dB bandwidth. The select pin of the control logic input can tolerate voltages above V+ up to 5.5 V. Logic high 1.8 V is guaranteed over the full V+ range that makes it compatible with many low voltage digital control circuits. The features of ultra small package size, wide V+ range, low on-resistance, low logic threshold, and switch isolation under fault condition make it an ideal device for battery operated devices to handle signals such as audio, video, data stream, and other high accuracy signals. • • • • • • • Isolation at V+ = 0 V and signal above V+ Logic input tolerates up to 5.5 V 1.6 V to 5.5 V operation voltage range Guaranteed 1.8 V VTH(high) at V+ = 4.5 V 0.008 % total harmonic distortion Low switch on-resistance 300 mA latch up current per JESD78 RoHS COMPLIANT BENEFITS • • • • Ultra small miniQFN8 package of 1.4 x 1.4 x 0.55 mm High fidelity audio switch Reed relay replacement Low power consumption APPLICATIONS • • • • • • • The DG2522 comes in a small miniQFN-8 lead package of 1.4 mm x 1.4 mm x 0.55 mm. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device termination and is 100 % RoHS compliant.
