Maxim Integrated MAX6126AASA21+ Ultra-High-Precision Voltage Reference

The MAX6126AASA21+ is a state-of-the-art ultra-high-precision voltage reference from Maxim Integrated, renowned for its stability and accuracy. This impressive component is designed to provide a precise reference voltage for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-accuracy instrumentation. The MAX6126 series ensures that precision applications maintain their integrity through fluctuations in temperature, time, and power supply variations.

At the heart of the MAX6126AASA21+ is its advanced bandgap circuit, which provides a fixed output voltage of 2.048V with an impressive initial accuracy of ±0.02%. This high level of precision is maintained over the operating temperature range of -40°C to +125°C, with a low temperature coefficient (tempco) of only 3ppm/°C, ensuring reliable performance in a wide range of environments and applications.

The device boasts an excellent low dropout voltage, allowing it to function optimally with minimal headroom above the output voltage. This makes it particularly suitable for battery-powered and portable applications where power efficiency is crucial. Additionally, the MAX6126AASA21+ features a low output noise of just 1.25µVp-p (0.1Hz to 10Hz), which contributes to the overall signal integrity in sensitive electronic systems.

The MAX6126AASA21+ also offers a high output current capability of ±15mA, making it versatile enough to act as a reference for multiple components in a circuit without the need for buffering. Its load regulation is as low as 12µV/mA, further illustrating its ability to maintain a stable output despite changes in load.

For added flexibility, the device includes a force-sense configuration that corrects for any voltage drops due to wire resistance, ensuring that the voltage at the load is always accurate. The MAX6126AASA21+ comes in a compact 8-pin SOIC package, making it easy to integrate into a variety of circuit designs without taking up significant board space.

Whether you're designing precision instrumentation, high-end audio equipment, or any other application that demands the utmost in voltage reference accuracy and stability, the MAX6126AASA21+ is an excellent choice that delivers consistent performance and reliability.
