Maxim Integrated MAX6126AASA50+ Ultra-High-Precision Voltage Reference

The MAX6126AASA50+ is an ultra-high-precision, low-noise, low-dropout voltage reference from Maxim Integrated. This device is part of a series of voltage references that are designed to provide a stable and accurate reference voltage for high-performance analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision circuitry. With its advanced design and robust feature set, the MAX6126 is an ideal choice for critical applications in medical, industrial, and high-end instrumentation.

This voltage reference features an impressive initial accuracy of ±0.02%, ensuring that precision is maintained right from the start. Its temperature coefficient is as low as 3ppm/°C, which translates to outstanding temperature stability over the full operating temperature range of -40°C to +125°C. This level of precision is maintained through a wide supply voltage range of 2.7V to 12.6V, making it versatile for various system designs.

The MAX6126AASA50+ also boasts an excellent low dropout voltage, typically 200mV at full load, which allows it to function effectively even with minimal headroom above the output voltage. This feature is particularly useful in battery-operated devices where power efficiency is crucial. Additionally, the device offers a low output noise of 1.25µVp-p (0.1Hz to 10Hz) and a low, 60µA (typical) quiescent current, further enhancing its suitability for noise-sensitive and power-conscious applications.

With a force and sense output that enables the reference to compensate for voltage drops due to load currents, this device can deliver its rated voltage accuracy at the point of load, not just at the output pin. The MAX6126AASA50+ comes in an 8-pin SOIC package and is fully specified over the extended industrial temperature range.

For designers looking for a reliable and high-precision voltage reference, the MAX6126AASA50+ from Maxim Integrated stands out as an excellent choice. Its combination of accuracy, stability, and low power consumption makes it a key component in applications requiring the highest level of precision.
