1. How to choose the right instrumentation amplifier?
The input common-mode voltage range, gain-bandwidth product, noise performance, power consumption, temperature drift, and common-mode rejection ratio (CMRR) should be considered when selecting an instrumentation amplifier to ensure that it meets the accuracy requirements of a particular application.
-
2. How do instrumentation amplifiers handle sensor signals?
Instrumentation amplifiers are used to extract low-level signals from sensors (e.g. thermocouples, pressure sensors) to provide high-precision amplification, and are particularly suited to applications that require accurate reading and amplification of weak signals, such as medical and industrial monitoring.
