Maxim Integrated MAX4078EUD - Precision, Low-Cost, Low-Voltage, High-Side Current-Sense Amplifier

The MAX4078EUD from Maxim Integrated is a high-performance, precision current-sense amplifier designed to monitor current in battery-powered systems, power-supply control, and other applications requiring high-side current monitoring. This device is perfect for situations where low voltage operation and cost are critical factors.

The MAX4078EUD operates from a single supply ranging from +2.85V to +28V, and can sense currents in systems with common-mode voltages from 0V to +28V, independent of the supply voltage. This feature allows the device to monitor battery cells or other low-voltage sources without the need for additional power supplies, making it an excellent choice for portable and space-constrained applications.

With its precision specifications, the MAX4078EUD boasts a low input offset voltage of only 250µV (max) and a low input bias current of 1µA (max), ensuring accurate current measurement even at low levels. The device also offers a wide input common-mode range of 0V to +28V, which is independent of the supply voltage, providing versatility and ease of use in various circuit configurations.

The MAX4078EUD is available in a compact 14-pin TSSOP package, making it suitable for space-saving designs. It also features a high gain accuracy of ±0.5% (max) and a wide bandwidth of 200kHz, which allows for fast response times in dynamic systems. This combination of precision and speed makes the MAX4078EUD ideal for overcurrent protection, power management, and battery charging applications.

Additionally, this current-sense amplifier is designed with an industry-standard pin configuration, which simplifies the design process and allows for easy integration into existing layouts without significant modifications. Maxim Integrated's commitment to quality and reliability ensures that the MAX4078EUD provides consistent performance in a variety of challenging environments.

For designers looking for a reliable, precise, and cost-effective solution for high-side current sensing, the MAX4078EUD from Maxim Integrated is an excellent choice that balances performance with affordability.
