The TL084CPWG4 is a general-use low-power JFET-input quad operational amplifier operating from a single power supply over a temperature range of –40°C to 85°C. It offers excellent operational characteristics and phase characteristics. This quad operational amplifier is suitable for many analog applications. It is suitable for single supply operation from 3V to 18V.

The TL084CPWG4 has excellent AC and DC characteristics including wide bandwidth, low noise figure, low power consumption, and high common-mode rejection ratio. It has a high open loop gain of 102db and an input voltage noise of 15nV/Hz. The output impedance is very low. It has a slew rate of 5V/us and a maximum closed-loop gain of 1000V/mV.

The TL084CPWG4 operates on a single supply and has a wide spectrum of applications in instrumentation, audio, and video. It is suitable for use in audio mixing consoles, video mixing consoles, video projectors, and for buffering and driving audio and video signals. It can be used as a low noise voltage gain/buffer in telecommunication and low-speed data acquisition systems, and can be configured as an active low-pass filter and as an inverting amplifier.

The TL084CPWG4 is designed to provide low power consumption, high common-mode rejection, wide bandwidth, and low bias currents. It is stable over a wide temperature range of –40C to +85C. The device has four separate input pins and a single output pin, which enable it to perform four independent operations.

The device consists of four independent JFET (Junction Field Effect Transistor) amplifiers, each with a common-mode input range extending to the negative supply voltages. Each amplifier is internally compensated with two feedback networks, and the output stage is designed to provide high speed, low output impedance, and low distortion operating with high transistor gain.

The working principle of the TL084CPWG4 is based on the use of FETs (Field-Effect Transistors) as a voltage controlled current source and a voltage source, with the source and drain connected to the positive and negative supply voltages, respectively. A positive potential imposed on the gate controls the current through the transistor and forms the basis of the amplifier. The output voltage is proportional to the input voltage, with a gain based on the ratio of the input current to the transconductance of the device.

The TL084CPWG4 has a wide spectrum of applications including, but not limited to, Linear Amplifiers, Instrumentation, OP Amps, Buffer Amps, and Active Filter Amplifiers, as well as A/D conversion, video gain and buffer amplifiers, low noise current source, and many other analog applications. It can be used as an adjustable amplifier, buffer, and gain controller when combined with a source-follower, such as a JFET or MOSFET.

The TL084CPWG4 is ideal for many audio, video, and analog applications that require low noise, low power consumption, high speed, and high accuracy. It offers excellent characteristics and phase response, and is suitable for single supply operation from 3V to 18V.
