The LF356H is a solid state instrumentation amplifier (InAmp) designed for precision applications. It features low offset, temperature drift, and gain accuracy. It is suitable for a wide variety of applications such as signal conditioning, strain gauge, bridge and unit acquiring. This article examines the practical applications and working principles of the LF356H.

Applications

The LF356H is a general purpose, low-power amplifying device that offers high accuracy and stability. It is ideal for a wide range of applications including:

• Sensor signal conditioning.
• Strain gauge.
• Bridge and unit acquiring.
• Analog signal conditioning.
• Data logging.
• Thermal instrumentation.

Due to its low-power consumption, high gain accuracy and temperature compensation, the LF356H is suitable for instrumentation and measurement systems, as well as signal conditioning for medical and industrial applications.

Working Principle

The LF356H is an integrated circuit that features two input channels (non-inverting and inverting) and two output channels (non-inverting and inverting). The non-inverting and inverting inputs are connected to the non-inverting and inverting outputs via a single gain stage, providing complete differential signal-path correction. This ensures high accuracy in terms of gain and offset. In addition, the LF356H includes an offset null, input bias current and output current limiting, and slew rate limiting, as well as temperature compensation.

The gain of the LF356H is determined by three internal passive components – two resistors (R1 and R2) and one capacitor (C1). The values of these components are configured by setting the ‘gainset’ switch, which reverses the polarity of the output stage and changes the values of the two resistors and the capacitor. By varying the ‘gainset’ switch, the gain of the LF356H can be fine-tuned for specific applications.

The LF356H features low offset, temperature drifts and gain accuracy, which makes it ideal for precision applications. The offset null of the device allows for precise trimming of both input and output offsets. The effective overload protection mechanism ensures the device operates at its optimum level even when exposed to high overloads. Furthermore, the RF oscillator limits the amplitude of any frequency response error. These features provide robust performance in a wide range of applications.

Conclusion

The LF356H is a versatile integrated circuit that has been designed for precision applications. It is suitable for a wide range of applications including sensor signal conditioning, strain gauge, bridge and unit acquiring, analog signal conditioning, data logging, and thermal instrumentation. Due to its low-power consumption, high gain accuracy and temperature compensation, the LF356H is ideal for instrumentation and measurement systems, as well as signal conditioning for medical and industrial applications. The gain of the LF356H is determined by three internal passive components, which can be configured by setting the ‘gainset’ switch. Additionally, its features such as offset null, input bias current and output current limiting, and slew rate limiting, as well as temperature compensation provide robust performance in a wide range of applications.
