Maxim Integrated MAX6191BESA Precision Voltage Reference

The MAX6191BESA from Maxim Integrated is a high-precision, low-noise voltage reference IC, renowned for its stability and accuracy. Designed for demanding applications that require a stable voltage reference, this component is ideal for high-performance data converters, precision power supplies, and as a reference for portable instrumentation.

Encased in a compact 8-pin NSOIC package, the MAX6191BESA provides a fixed output voltage of 5V with an impressive initial accuracy of ±0.02%. Its low temperature coefficient of 3ppm/°C ensures minimal deviation across a wide temperature range, making it a reliable choice for systems that operate under varying environmental conditions.

The device boasts an excellent load regulation of 13μV/mA and a low supply current of 400μA, which is beneficial for power-sensitive designs. The low dropout voltage of the MAX6191BESA means it can maintain its output stability even with minimal difference between the input and output voltages, which is particularly useful in battery-operated devices where power efficiency is critical.

Another feature of the MAX6191BESA is its low output noise of just 15μVp-p (0.1Hz to 10Hz), making it an excellent choice for high-resolution analog-to-digital and digital-to-analog conversions where noise can significantly impact accuracy. The device's ability to sink and source current up to 5mA provides additional design flexibility, catering to a wide range of load conditions.

For enhanced system reliability, the MAX6191BESA includes a force-sense connection that corrects for any voltage drops due to PCB trace resistance, ensuring that the output voltage remains accurate at the load point. Compatibility with TTL and CMOS makes this voltage reference easy to integrate into a variety of digital systems.

Maxim Integrated's commitment to quality is evident in the MAX6191BESA's design, which is built to meet the stringent requirements of precision applications. Whether you're designing for industrial, medical, or consumer electronics, this voltage reference will help maintain the integrity and performance of your system.
