Power Performance Tradeoffs in Op Amps (.PDF Download)
High performance with low power consumption: This requirement is coming to bear in more and more applications, especially when it comes to mobile, battery-operated devices. Particularly in the times of IoT, Industry 4.0, and digitalization, these handhelds make many aspects of daily life easier. This is true in applications ranging from mobile vital sign monitoring to the monitoring of machines and systems in an industrial setting. Demands for higher performance and maximum battery life also are seen in end-user products, such as smartphones and wearables.
The limited battery energy available for supplying power necessitates efficient components with minimal current in active mode to maximize device runtime. Alternatively, lower power consumption allows one to achieve the same battery life with a lower capacity battery, reducing size, weight, and cost.
