Selection Of Smart Sensor Components And Power Supply Circuit

The selection of components must be sufficient, as long as the component indicators are within the required range, and the rest is the circuit design problem. Power supply is a problem that must be encountered in the process of sensor circuit design. Don’t pursue unreachable power supply indicators, but choose an op amp with a better common-mode rejection ratio, and use the most common switching power supply designed with a differential amplifier circuit. The device can meet your requirements. The decoupling of the power supply must be designed reliably and follow the requirements of the device manual, rather than less.
