The MAX4039EUB+ is an op-amp instrumentation amplifier with a low-noise, low-distortion, wide-bandwidth JFET input topology. With a precise gain of 150dB and a gain bandwidth product of 900kHz, it is well-suited for various precision audio, medical and communications applications. The device also features high-speed CMOS outputs and a complementary-output configuration.

The MAX4039EUB+ is designed to meet the requirements of instrumentation, process control, and audio applications, with low noise and distortion levels. This op amp provides rail-to-rail output swing and input common-mode range. The device features an internal offset adjustment, extended common-mode range, internal gain resistors, and rail-to-rail outputs.

The MAX4039EUB+ op amp can be used in a variety of instrumentation and signal-capturing applications that include voltage measurement, audio signal processing, switched-capacitor filter circuits, low-noise biasing, and high-precision phased-locked loops. It is also suitable for use in medical and communications applications, where low noise and distortion are important. The device offers a wide power supply range of 2.5V to 20V, and due to its low power consumption, the device can be operated with a single power supply while meeting the power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR) requirements of the application. The device is available in an 8-pin ultra-small, lead-free (MSOP) package.

The MAX4039EUB+ op amp offers an improved noise performance, with an input voltage noise density of 5nV/√Hz and an input current noise density of 1pA/√Hz. Low offset voltage and low drift specifications help the device to achieve accurate signal conversion and transfer. With a unity-gain bandwidth of 3GHz and a slew rate of 8V/μs, the device is capable of providing fast settling time without sacrificing accuracy. Furthermore, the device can operate over a wide temperature range of -40°C to +125°C.

The MAX4039EUB+ operates using a non-inverting topology, with the input connected to the inverting input and the output connected to the non-inverting input. This allows the device to amplify the difference between the two inputs. The input common-mode range of -3V to +3V makes the device suitable for single-ended and differential-input signals. The wide unity-gain bandwidth allows for high-frequency response and fast settling time, while the slew rate capability of 8V/μs ensures the accuracy of the signal conversion.

The MAX4039EUB+ op amp features an internal gain adjustment pin (GAIN) that allows the user to adjust the device’s gain. This allows the device to be adapted to a wide range of applications. Additionally, the device has an internal compensation circuit that ensures stable operation over a wide range of temperature and operating currents. The device also features temperature-independent offset voltage, low drift, and wide input common-mode range.
