Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
Guaranteed by design.
Note 2:
Maximum output current (sinking/sourcing) in which the gain changes by less than 0.1%.
Note 3:
This specification represents the typical temperature coefficient of an on-chip thin film resistor. In practice, the temperature
coefficient of the gain for the MAX4194 will be dominated by the temperature coefficient of the external gain-setting resistor.
编译自semiengineering 业界越来越关注人工智能的功耗问题，但这个问题并没有简单的解决方案。这需要深入了解应用、半导体和系统层面的软件和硬件架构，以及所有这些的设计和实现方式。每个环节都会影响总功耗和提供的效用。这是最终必须做出的权衡。 但首先，必须解决效用问题。电力是否被浪费了？“我们将电力用于有价值的用途，”Ansys（现为新思科技旗下公司）产品营销总监 Marc Swi...[详细]
