High-Speed: High-Side Current Sense Reference Design
Description
This reference design is a high-speed current-to-voltage circuit. It is optimized for current-sense applications that require high-speed current measurements in the positive supply rail for voltages from 5 to 30 V. This design will reduce the common-mode voltage from 30 V and produce an output voltage centered at 2.5 V for sampling with an analog-to-digital converter (ADC). The output common mode can be easily changed by using different precision references.
