The MAX4376FAUK-T is an ultra-low input current compatible instrumentation amplifier, designed to replace traditional designs used for medical and industrial instrumentation applications. Offering very low input currents for low noise and high accuracy, the MAX4376FAUK-T is ideal for use in a variety of high-end instrumentation and medical applications, such as thermoelectric measurements, pressure sensors, and ECG equipment.

The MAX4376FAUK-T incorporates two dedicated differential amplifier blocks, one pair of low input current buffers, and a high-speed, high-voltage rail-to-rail input/output operational amplifier (OPAMP). The operational amplifier has a noise-rejecting architecture and is based on an industry-standard low voltage IC process, providing industry-leading accuracy performance with low power dissipation.

The MAX4376FAUK-T operates with a supply voltage range of +7.5V to +20V, and has a maximum input voltage of 5.25V. This wide range of supply voltage allows for easy application in a wide variety of applications. The amplifier also features a high input impedance, along with a low-noise, highly linear input current (IP - 20nA). The low input current is ideal for low-noise sensing applications, such as ECG recording. The amplifier is also designed to operate with an input voltage range of up to 5.25 V.

The design of the MAX4376FAUK-T is optimized for fast settling time and high accuracy, as well as a low input bias current. The input common-mode voltage is adjustable via an external resistor. The amplifier also offers excellent temperature stability, with a temperature coefficient (TC) of 1.5ppm/°C. This provides exceptionally linear gain over the entire temperature range.

The MAX4376FAUK-T also features protection against transients, with protection diodes integrated into the device for ESD protection and overvoltage protection. The amplifier also has an integrated power-down circuit to shut down the device in the event of overvoltage, short-circuit, or thermal stress.

The MAX4376FAUK-T\'s combination of exceptional accuracy, low power consumption, robust design, and ESD protection make it ideal for high-end, high-accuracy instrumentation applications. The device is suitable for use in medical imaging, instrumentation, automotive, and industrial environments, as well as general-purpose and power management applications. Its ultra-low input current eliminates the need for external buffers and supports reliable performance even in the presence of high-speed noise and large input signals.
