OP Amp 735AIDBVRG4 – Instrumentation, Buffer Amp Application Field and Working Principle

The OP Amp 735AIDBVRG4 is part of the linear amplifier family, specifically intended for use in instrumentation and buffer amp applications. This op amp is designed to be used in high performance systems for a variety of applications. The 735AIDBVRG4 is manufactured by Texas Instruments and offers high accuracy, fast settling and wide bandwidth, making it ideal for precision applications such as audio signal processing and measurement, with a bandwidth of 14MHz and a typical settling time of 0.005%.

Application Field

This amplifier can be used in a range of applications, including instrumentation, military and aerospace, data acquisition and other closed loop linear control systems. It is particularly suitable for applications requiring low noise, low power and high accuracy, such as audio signal processing, scientific research instrumentation and measurement, operational amplifiers and data acquisition systems.

Working Principle

The OP Amp 735AIDBVRG4 is composed of several components including a differential amplifier, an output buffer, a voltage regulator and a power supply.The differential amplifier stage comprises a pair of transistors, one PNP and one NPN. The PNP transistor has two collectors, while the NPN transistor has only one collector. This configuration ensures that the voltage at the base of the PNP transistor remains constant, while an input voltage varying between zero volts and +12 volts is applied to the base of the NPN transistor, resulting in a constant differential voltage between the transistors.The amplifier\'s output buffer comprises an output transistor and a resistor. This transistor is responsible for making the output current independent of the differential voltage. The output buffer has two modes: single-ended, where the output is connected to only one voltage source, and differential, where the output is connected to two voltage sources.The voltage regulator is a type of device that controls the current to prevent over or under-voltage. It is particularly useful in applications where precision and stability are required. The 735AIDBVRG4 has a voltage regulator with a maximum voltage of 6.2V and a minimum voltage of 0.1V.The power supply of the 735AIDBVRG4 is supplied by an external voltage source that is connected to two terminals on the op amp. The power supply can range from +12V to -12V.

Conclusion

The OP Amp 735AIDBVRG4 is a linear amplifier specifically designed for applications such as instrumentation, military and aerospace, data acquisition and other closed loop linear control systems. It is a high performance amplifier with a bandwidth of 14MHz and a typical settling time of 0.005%. It has low noise and a low power consumption, making it ideal for precision applications. The power supply to the amplifier is provided by an external voltage source and is adjustable from +12V to -12V.
