Current sense amplifier comparison and error tool
This Excel calculator provides a comparison between two and five of our standard current sense amplifiers, delivering a chart containing the basic parameters of each device. This calculator also takes system condition inputs from users such as common-mode voltage, supply voltage, shunt resistor value and tolerance, and then plots error curves across an adjustable current range. In addition, the calculator outputs a maximum shunt value (mΩ) based on the calculated full-scale input voltage divided by maximum measurement current.
- Customizable shunt resistor and voltage parameters
- Configurable error versus current graph
- Shunt power dissipation in milliwatts
