The MAX4372FESA+ op amp is designed for precision applications, with low input noise, fast settling, and laser-trimmed gain accuracy. The op amp is a low-voltage, single-supply precision instrumentation amplifier with programmable gains of 1, 2, 4, 5, 8 and 10V/V, adjustable ac and dc common-mode rejection and improved linear output current sourcing and sinking capability, making it well-suited for industrial systems and portable equipment applications. Its low noise make it an ideal choice for applications in the consumer, industrial, computer, and medical industries.

This instrumentation amplifier provides precision gain accuracy with 0.5% guaranteed gain accuracy (max) when set externally. Due to its low input bias current, the offset voltage is extremely low, at 1mV (max). Furthermore, the input noise is low due to careful layout, making it ideal for high resolution applications such as medical instrumentation. Additionally, the combination of a dynamically stable gain setting scheme and externally programmable gain setting capability allows for gain to be adjusted with minimal performance penalty over temperature variation and time.

The MAX4372FESA+ is designed to work on barely any power source with a single 3.2 to 24V supply and only 3.2mA of quiescent current. Because of its single-supply operation, it can be used in many designs with low DC circuits. With only a few external components, the MAX4372FESA+ can be configured to provide additional flexibility such as a digital gain controller.The precision instrumentation amplifier is able to provide fast settling time of 85ns (to 0.1%) and excellent common mode input range that extends beyond the positive and negative power supply rails. It has low temperature coefficient of zero drift and low phase mismatch over temperature.

When performing precision tasks such as sensor data acquisition, the MAX4372FESA+ can deliver high accuracy and speed throughout its operation. Its performance is also highly consistent over temperature-induced shifts and time. Due to its peaking design technique, the precision amplifier offers superior common-mode-rejection and gain accuracy. The MAX4372FESA+ can be used in linear, power and signal conditioning related applications, to increase measurement accuracy, such as in high speed data converters, precision voltage regulation, transimpedance amplifiers, thermocouple signal amplifiers, low noise filters, etc.

In conclusion, the MAX4372FESA+ op amp is a low-voltage, single supply precision instrumentation amplifier with programmable gains of 1, 2, 4, 5, 8 and 10V/V and adjustable ac and dc common-mode rejection. Its small size, low power consumption and low quiescent current make it ideal for applications in the consumer, industrial, computer, and medical industries, where high accuracy and speed is needed. Its small size and low offset makes it desirable for many applications, particularly when precision is paramount.
