Applications

The low power TL084IDR can be used in a wide range of applications, such as industrial instrumentation and process control, medical equipment, and professional audio equipment. It is ideal for use in instrumentation amplifiers, DC measurements, instrumentation amplifiers, and lifelike audio amplifiers due to its low power consumption and wide input voltage range. Additionally, these op-amps can be used in high precision analog circuits such as voltage controlled oscillators (VCOs), filters, and sample-and-hold circuits. It is also suitable for use in low noise data acquisition systems and low-noise analog systems.

Working Principle

The TL084IDR is a four-quadrant multiplier that combines two internal op-amps and two voltage-controlled current sources to perform operations. It utilizes a feedback system using the output voltage to adjust the current flowing through the input. The current flows through the feedback resistor network, and then the current flows through the op-amp input. The op-amp output voltage is dependent on the differential input voltage, and is multiplied by the current flowing through the input of the op-amp. This current flow produces the output voltage. The output voltage is then fed back into the input of the op-amp, allowing the op-amp to adjust the current flowing through the input to produce the output voltage. This feedback system ensures that the output voltage is proportional to the input voltage.

Instrumentation amplifiers are frequently used in a wide range of applications, and the TL084IDR can be used in such applications due to its low power consumption and wide input voltage range. It is suitable for use in DC measurement and low-noise analog systems, allowing users to accurately measure and process signals within desired parameters. It also has a high output current, high slew rate and low input bias current, making it ideal for use in AC measurements and high precision analog circuits.
