The TL074CDRG4 is a device from Texas Instruments’ high-performance JFET-input operational amplifier series. It can be used in a variety of applications, most commonly in instrumentation, signal conditioning, and automated test equipment. The device is a low-power, low-noise monolithic op-amp, offering an improved signal-to-noise ratio and distortion that is optimized for audio devices. Additionally, its low-bias current reduces power consumption and lessens temperature-related stability issues.

Application Fields

The most typical application of the TL074CDRG4 is in instrumentation. This amplifier features an enhanced slew-rate that makes it ideal for producing the high-resolution signals needed for accurate and detailed lab instrumentation. It’s also often used amplifying audio signals, as the combination of slew-rate and low-noise circuitry makes it well-suited for sound reinforcement, CD/VCR players, and other similar types of equipment.

The TL074CDRG4 has a wide voltage range, capable of amplifying signals up to ±22V. This makes it a viable solution for mixed-signal processing and data acquisition-style applications. Additionally, its low-power (1.3mA) and low-noise (0.5nV/√Hz at 1MHz) properties make it ideal for digital signal processing. It is important to note that this device is not intended for designs that require rail-to-rail output unless a clipper circuit is used.

Working Principle

The TL074CDRG4 is available in three package options: DIP-14, SOIC-14, and TSSOP-14. The device operates on any single supply voltage ranging from 3V to 22V, or on a dual supply with inputs and outputs between ±1.5V to ±11V. The guaranteed 14V maximum supply voltage gives the device a high-input voltage range and output performance. The input bias current is a minimum of 0.5nA, with a minimum open-loop gain of 115dB.

The power consumption of the TL074CDRG4 is low, with a quiescent current of 1.3mA per amplifier. The device requires a maximum power supply current of 10mA to achieve a certain performance. Additionally, the TL074CDRG4 can be utilized as an analog multiplexer/demultiplexer, as the lateral channels can be used for any high-speed conversion angle. A multiplexer can be used to switch an input from a variety of sources into a single output.

The TL074CDRG4 features low-noise amplification that is designed for a reduced noise level for a higher signal-to-noise ratio. This can be used in applications that require a low-noise differential amplifier, such as detection and mixing circuits. The device includes an internal shutdown input which offers a combination of low-power and low-noise in a single device.

The TL074CDRG4 also offers an adjustable common-mode input, which enables users to internally achieve a balance between voltage levels. The device also provides excellent protection against overload and fast settling time behaviour, making it suitable for high-speed and precision applications.

Conclusion

In conclusion, the TL074CDRG4 is an ideal choice for instrumentation, signal conditioning, and automated test equipment due to its enhanced slew-rate and low-noise circuitry. It can also be used in many audio-related applications, as well as in virtual instrumentation and data acquisition systems. Other features that set it apart from other device in the same family are its adjustable common-mode input and good overload protection. With low power, low-noise operation, and good overload protection, the TL074CDRG4 is a great choice for many applications.
