Maxim Integrated MAX6126A30 Ultra-High-Precision Voltage Reference

The MAX6126A30 from Maxim Integrated is an ultra-high-precision, low-noise, series voltage reference that is ideal for use in high-end applications where a stable and accurate voltage reference is critical. This device offers an impressive output voltage of 3.0V, making it suitable for a wide range of applications, including medical devices, precision instrumentation, and data acquisition systems.

One of the standout features of the MAX6126A30 is its exceptional accuracy. With an initial accuracy of ±0.02% (maximum) and a low temperature coefficient of 3ppm/°C (max), this voltage reference ensures reliable performance even under varying environmental conditions. This precision is maintained over time, thanks to the low long-term stability of 50ppm/1,000 hours (max).

In addition to its accuracy, the MAX6126A30 boasts a low output noise of just 3µVp-p (0.1Hz to 10Hz) and a low supply current of 800µA (max). These features make it an excellent choice for noise-sensitive applications where power efficiency is also a concern.

The device is designed to be versatile and user-friendly, offering a dropout voltage as low as 200mV (max) and an output current capability of 10mA. This means it can maintain stable output even with minimal headroom above the output voltage, and it can drive moderate loads directly. The MAX6126A30 also includes a force-sense configuration, which allows for remote voltage sensing to compensate for voltage drops due to load or line resistance, ensuring the accuracy of the voltage delivered to the load.

For added flexibility, the MAX6126A30 comes in a small 8-pin SO package, as well as a tiny 6-pin SOT23 package, making it suitable for space-constrained applications. The device operates over a wide temperature range of -40°C to +125°C, ensuring reliable operation in a variety of environments.

Overall, the MAX6126A30 from Maxim Integrated is a robust and reliable solution for applications requiring a high-precision, low-noise voltage reference with minimal drift over time and temperature.
