When designing circuits that rely on precise signal amplification, one of the most common components used is the operational amplifier (op-amp). The AD623ARZ, a high-precision instrumentation amplifier, is widely popular in applications ranging from sensor signal conditioning to medical devices, audio processing, and more. However, like any piece of electronic equipment, it can encounter problems that affect its performance. If you're facing issues where your AD623ARZ is not amplifying correctly, understanding the possible causes and solutions is essential.
