Working Principle

The TL084BIPT is an operational amplifier with a common-mode input voltage range of 0V to VDD. The output can swing within 0.3V of either Vss or Vdd, making the amplifier suitable for single-supply operation. The amplifier has two JFET ( Junction Field Effect Transistor) input stages. Each of these stages amplifies the differential input voltage and produces an output voltage which is proportional to the input voltage. These input stages are followed by a current feedback circuit which further amplifies the differential input voltage, introduces a controlled feedback, and ensures a constant bandwidth over the entire output voltage range. The TL084BIPT is designed to operate with a wide range of supply voltages and is designed to operate with a minimum supply voltage of 1.8V and an operating temperature range of -55 °C to +125 °C.

The amplifier has several internal protection features that protect the device from destruction by excess temperature or electrical overload. The amplifier also includes an output stage which can provide a maximum power dissipation of 75mW. The output stage also has a rise and fall time of 2.5ns, making the amplifier suitable for applications requiring high frequency operation. The TL084BIPT is available in 8-pin PDIP and 8-pin SOIC packages, making it suitable for a variety of applications.
