The MAX4238ASA+T is a monolithic linear amplifier with a high input dynamic range and low noise that makes it ideal for a wide range of applications, most notably as an instrumentation amplifier and for low-frequency signal conditioning. The MAX4238ASA+T is designed around a new high-speed, high-gain, highly linear BiCMOS architecture, which employs fully differentiated differential amplifiers to provide above-average performance, low distortion, and excellent frequency response. The amplifier employs low-noise RF and CMOS-based circuitry to ensure the best possible performance at high frequencies.

The MAX4238ASA+T’s high input dynamic range, 35 dB, makes it suitable for use as a buffer amplifier or an instrumentation amplifier. It is also excellent for low-frequency signal conditioning, as that range includes instrumentation amplifiers and more complex signal-conditioning circuits. It also works with precision components, such as opto-isolators, to ensure accuracy and stability over a wide range of temperatures. The MAX4238ASA+T also features high linearity and high CMRR, which make it ideal for applications such as high-resolution data conversion and acoustic measurement.

The MAX4238ASA+T’s low noise makes it suitable for high-fidelity audio applications. The audio frequency response is ± 0.05 dB from DC to 20 kHz, and it has a typical low noise of 2.5 uV. The amplifier also offers low high-frequency distortion, with a high-frequency distortion of 0.002% at 1 kHz, making it ideal for audio applications.

The MAX4238ASA+T is also suitable for power-supply and energy-storage applications. It has an integrated functional power supply, with a wide input voltage range of 5 V to 36 V and a low quiescent current of 6mA. The amplifier also has a wide output voltage range of -20 V to +20 V and can provide up to 3 A of output current, making it suitable for energy storage applications.

The MAX4238ASA+T also includes a variety of safety features that make it a great choice for any application. The amplifier has an overvoltage protection circuit that monitors the input voltage and shuts off if the input voltage exceeds its safe voltage range. The amplifier also features a thermal protection circuit that prevents the amplifier from overheating, by cycling the power on and off if the die temperature exceeds its safe operating temperature. It also has current-limiting circuitry that prevents the amplifier from drawing too much current from the input power supply, which protects both the amplifier and the power supply from damage.

The MAX4238ASA+T is well suited for many applications, including instrumentation amplifiers, low-frequency signal conditioning, and audio applications. Its wide dynamic range, low noise, and high linearity make it a great choice for any application that requires precision, high accuracy, and low distortion. The MAX4238ASA+T’s wide range of safety features makes it a safe choice for any application, no matter how demanding.
