The LF398H/NOPB is an 8-pin package operational amplifier, specifically designed for use in industrial, professional and scientific applications. It features excellent linearity, low offset, high slew rate, and low power consumption. This makes it suitable for applications such as measurement, control, and data acquisition.

Application Fields

The LF398H/NOPB is ideal for instrumentation, gain and phase control, precision measurement, analog compensation, and filter applications. It features low offset voltage and slew rate, making it suitable for a variety of applications where accuracy, stability and precision are paramount. It is also ideal for applications where a high levels of ac and dc gain are required, such as high speed communication, medical imaging systems, automotive testing systems and other industrial equipment.

Working Principle

The LF398H/NOPB operates based on the principle of negative feedback. It has an input stage, differential amplifier, and output stage. The input stage is comprised of two metal-oxide-semiconductor field-effect (MOS) transistors which amplify the incoming signal. The output stage of the LF398H/NOPB maintains a constant gain over a wide frequency range, with an operating temperature range from -55°C to +125°C. The output current is proportional to the difference between the input voltage and the output voltage, and the resulting current is used to control the gain of the output stage. The differential amplifier amplifies the difference between the two inputs, and this voltage is used to control the gain of the output stage.

The LF398H/NOPB can be used in a wide variety of applications, including instrumentation and precision measurement, filters, and high speed communications. Its excellent linearity, low offset, and low power consumption make it ideal for applications where a high level of performance is required. Additionally, the LF398H/NOPB is available in both 8-pin PDIP and SOIC packages, making it easy to integrate into both PCB boards and surface mount designs.
