DescriptionThe ADG849 has the following features including (1)rail-to-rail operation;(2)automotive temperature range: 40°C to +125°C;(3)typical power consumption (<0.01 W);(4)High current carrying capability:400 mA continuous current,600 mA peak current at 5 V.
The ADG849 is a monolithic, CMOS SPDT (single pole, double throw) switch that operates with a supply range of 1.8 V to 5.5 V. It is designed to offer ultralow on-resistance values of typically 0.5 . This design makes the ADG849 an ideal solution for applications that require minimal distortion through the switch. The product also has the capability of carrying large amounts of current, typically 600 mA at 5 V operation.Each switch of the ADG849 conducts equally well in both directions when on. The device exhibits break-before-make switching action, thus preventing momentary shorting when switching channels.The product is available in a tiny, 6-lead SC70 package, making it the ideal candidate for space-constrained applications.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time.
The ADG849 described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
