The amplifier is particularly well suited for high-accuracy, low-level signal processing for applications such as field test and measurement.

This instrumentation amplifier utilizes an advanced design that combines two channels and no external components. It offers excellent accuracy, stability and many other features. The THS4221DR can operate in unity gain configuration, or in a gain range of 1 to 1000. It also provides excellent linearity, low distortion, and wide frequency response. Additionally, the amplifier has a high monotonic accuracy, excellent common-mode rejection ratio (CMRR), and wide band noise immunity. Moreover, the THS4221DR is extremely low-power and requires no external power supply.

The working principle of the THS4221DR is based on applying a feedback scheme to both of its differential inputs. The feedback scheme enables the amplifier to achieve its high gain accuracy, low noise, and wide frequency response. The amplifier’s inputs are buffered from the output by a differential amplifier and an additional stage which buffers the differential stage against external loading, providing a much improved transient response and lower distortion. The resulting signal is filtered and then shifted, so that an independent gain control can be applied to it. Finally, the output is buffered again and then fed back through a feedback loop which provides a highly accurate gain.

The THS4221DR is a highly useful instrumentation amplifier that can provide low-power, high-accuracy performance. Furthermore, the amplifier is extremely reliable and offers excellent noise performance and superior accuracy. As such, it is ideal for precision applications in various fields, from electrical and mechanical measurement systems, to motor control and data acquisition.
