DG3257

www.vishay.com DG3257 Vishay Siliconix 700 MHz, -3 dB Bandwidth; Single SPDT Analog Switch DESCRIPTION DG3257 is a low RON, high bandwidth analog switch configured in single SPDT. It achieves 5  switch on resistance, greater than 700 MHz -3 dB bandwidth with 5 pF load, and a channel to channel crosstalk at -32 dB and isolation at -33 dB. Fabricated with high density sub micro CMOS process, the DG3257 provides low parasitic capacitance, handles bidirectional signal flow with minimized phase distortion. Guaranteed 1.4 V logic high threshold makes it possible to interface directly with low voltage MCUs. The DG3257 is designed for a wide range of operating voltages from 1.65 V to 5.5 V that can be driven directly from one cell Li-ion battery. On-chip protection circuit protects again fault events when V+ goes zero. Latch up current is 300 mA, as per JESD78, and its ESD tolerance exceeds 6 kV. Packaged in ultra small μDFN6L (1 mm x 1 mm), it is ideal for portable high speed mix signa...
