DG3257
DG3257 is Single SPDT Analog Switch manufactured by Vishay.
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 d B bandwidth with 5 p F load, and a channel to channel crosstalk at -32 d B and isolation at -33 d B. 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 m A, as per JESD78, and its ESD tolerance exceeds 6 k V.
Packaged in ultra small μDFN6L (1 mm x 1 mm), it is ideal for portable high speed mix...
