Single-ended to differential converter can use low noise fully differential amplifier GX8138, compatible with AD8138

In electronic circuit design, the realization of single-ended signal to differential signal conversion is a common task, high-performance operational amplifiers play an important role in this regard, whether it is in the field of industrial automation control, medical equipment or consumer electronics, etc., for the system‘s performance enhancement and stability to provide protection.

The low-noise fully differential amplifier GX8138 features high accuracy and low distortion, and when used as a single-ended to differential converter, ensures that the converted differential signal maintains the accuracy and integrity of the original single-ended signal, satisfying applications that require high-quality signal transmission, such as high-speed communications and audio processing.

The GX8138 can be used as either a single-ended to differential amplifier or a differential to differential amplifier, and is as easy to use as a typical operational amplifier, with greatly simplified differential signal amplification and driving. The amplifier has low input noise, a -3dB bandwidth of 300MHz, and provides differential signals with lower harmonic distortion than existing differential amplifiers.The GX8138 utilizes internal common mode feedback and external gain feedback to provide relatively good gain and phase matching.

Its high bandwidth capability allows the GX8138 to accommodate a wide frequency range of single-ended signals and efficiently convert them to differential signals. It provides stable and reliable performance whether processing low-frequency control signals or high-frequency RF signals.

With good distortion performance, the GX8138 is also an ideal driver for ADCs in communication systems, driving 10-bit to 16-bit converters at higher frequencies. The high bandwidth and IP3 characteristics make it suitable for use as a gain module in IF and baseband signal chains. Excellent detuning and dynamic performance make the device well suited for a variety of signal processing and data acquisition applications.The GX8138 is available in SOIC and MSOP packages and operates over the -40°C to +125°C temperature range.
