The AD629BRZ is a linear instrumentation amplifier, a type of integrated circuit which, when used with external components, can be configured to produce an analog signal-type output and measure differential input voltages. The instrumentation amplifier is commonly used in industrial, scientific, analytical and medical applications, such as biomedical signal acquisition and conditioning, instrumentation systems, data acquisition and signal processing. It can be used to measure electrical signals over a wide range of amplitudes and can provide higher gain, wider dynamic range and better stability than a standard operational amplifier or buffer amplifier.

The AD629BRZ is implemented in a five-pin SOT-23 package and consists of three operational amplifiers and two resistors. The input stage consists of a differential amplifier and provides input impedance of more than 10¹⁴ ohms, while the output stage contains another differential amplifier and provides a high degree of accuracy and isolation. The AD629BRZ also features an on-chip, high quality lowpass filter that helps reduce noise. In addition, it provides protection against reverse and overvoltages, allowing for reliable operation in extreme conditions.

The AD629BRZ has a working principle based on the theory of negative feedback, wherein the output voltage is proportional to the difference between two input voltages. It measures a differential input voltage and amplifies it over a specified bandwidth, resulting in an amplified output that can be used in a variety of applications. The instrumentation amplifier can be used to measure electrical signals over a wide range of amplitudes, providing for better accuracy and sensitivity than a standard operation or buffer amplifier. In addition, the AD629BRZ provides reliable operation in extreme conditions, such as in high humidity or temperatures up to 125° C.
