The INA128P is a dual, high-input impedance instrumentation amplifier that offers a wide bandwidth and low offset voltage drift. It has been specifically designed to provide accuracy and performance-critical applications like strain gages and precision medical instruments. This article looks at the application field and working principle of the INA128P.

Application Field of INA128P

The INA128P amplifies low-level differential signals from strain gage bridges and is ideal for applications such as pressure and load sensors, bridge amplifiers, flow meters, and transducer interfaces. It features voltage output and can be used with a variety of input sources such as strain gages, thermocouples, and other types of transducers.

The INA128P is suited to medical instruments due to its high input impedance and small size. It also offers excellent drift stability, even in high humidity environments, making it suitable for a wide range of medical and laboratory applications. The INA128P can be used in a variety of medical applications, such as cardiac pacemakers and EEG electrodes, and is also suitable for a variety of laboratory applications, including strain gage testing and biofeedback.

Working Principle of INA128P

The INA128P operates on a three-stage, differential amplifying principle. The input is applied to a differential input stage where a differential input stage of MOS transistors is used. The differential input stage is then followed by an intermediate gain stage, which amplifies the signal and increases the common-mode rejection ratio. Finally, the last stage is the output amplifier stage, which buffers the output and provides a rail-to-rail output.

The INA128P also includes a number of additional features, such as a low noise input stage and a temperature compensated power supply. These features enable the INA128P to offer excellent accuracy and performance, even in electrically noisy or high-temperature environments.

The INA128P is a dual channel device, meaning it can be used to amplify both low-level differential signals and full-scale differential signals. The device is available in a variety of packages, including SOP and Leadless chips, and can be mounted to a variety of surfaces, from PC boards to daughter boards.

The INA128P is a very versatile device and can be used for a variety of applications, from strain gage sensing to medical instrumentation. It offers excellent accuracy and performance, even in high temperature and noise environments, making it ideal for precision applications.
