THS4061IDGNR is a high-performance operational amplifier device that is widely used in various modern linear amplifications and instrumentation applications. It comes in two sizes, the DGN and DGO, each with a generous operating voltage range of 3.3V - 18V. The device features an output voltage swing up to 11V, extremely low noise of 0.1µVrms, and high common-mode rejection rate (CMRR) and power supply rejection rate (PSRR) of 110dB, providing reliable and distortion-free amplification performance.

The THS4061IDGNR is an ideal solution in applications such as instrumentation amplifiers, automotive audio systems, audio recording applications, low-frequency amplifier measurements, and general precision-grade amplification requirements. Its high-speed operating frequency (fT) of greater than 6MHz and low input bias current of 50pA further improve the performance of the device in differential gain and phase applications.

The working principle of the THS4061IDGNR is very simple. The device utilizes a wide-band frequency gain that provides an amplification range from DC to high frequencies. It includes an internal differential-amplification with high common-mode rejection at frequencies up to 500Mhz. It also comes with a high gain-bandwidth product of 10MHz, making it suitable for many signal-processing applications. Its single-ended output impedance is only 27Ω, thus providing high-sensitivity and overload protection, as well as improved signal resolution.

The THS4061IDGNR is suitable for both single-ended and differential signal applications. As a single-ended amplifier, the device operates as a standard non-inverting amplifier, the signal is applied to the non-inverting input pin (IN+) and the inverted input pin (IN-) is connected to the GND terminal, when the signal is amplified, it is see through the output terminal (OUT). As a differential amplifier, both inputs are connected to the signal source, thereby amplifying the differential voltage applied to them. The individually adjustable gain adjustment of the device allows one amplifier to properly implement both single-ended and differential configurations.

The THS4061IDGNR can also be used in active filters and oscillators. For the first application, the device amplifies the signal’s frequency components and upon proper biasing and gain control can shape the frequency response of the filter. For the second application, the THS4061IDGNR can be used to produce sinusoidal and square wave signals thanks to its high-gain and high-frequency characteristics.

In conclusion, the THS4061IDGNR is a versatile device that can be used in many linear-amplification and instrumentation amplifiers, audio recording, sound systems, and general-purpose applications. It offers excellent input impedance, high power gain and wideband gain, good noise performance, low power consumption and good common-mode rejection characteristics, improving the performance of any system incorporating the device.
