Maxim Integrated MAX6126BASA41+T Ultra-High-Precision Voltage Reference

The MAX6126BASA41+T from Maxim Integrated is an ultra-high-precision, low-noise, series voltage reference that is ideal for use in high-performance data converters, precision voltage sources, and other demanding applications. This device offers a stable and precise reference voltage, with an impressive initial accuracy of ±0.02% and a low temperature coefficient of 3ppm/°C (max) over the full automotive temperature range of -40°C to +125°C.

Encased in a compact 8-pin SOIC package, the MAX6126BASA41+T is designed to deliver a fixed output voltage of 4.096V, which is a common reference voltage for analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). Its output is capable of sourcing and sinking up to 10mA of output current, providing flexibility in a wide range of applications.

The device boasts an excellent low dropout voltage, typically just 200mV at full load, which allows it to maintain stable output even with minimal input-to-output differential. Moreover, it features a low output noise of 3µVp-p (0.1Hz to 10Hz) and a fast settling time, making it an excellent choice for precision applications where noise and stability are critical.

One of the key features of the MAX6126BASA41+T is its low power consumption, drawing as little as 1.5mA of supply current, thereby making it suitable for battery-powered and portable devices where power efficiency is a priority. Additionally, this voltage reference comes with a force-sense capability, ensuring that the reference voltage is accurately delivered to the load, compensating for any voltage drop in the circuit.

The device also includes a shutdown mode, which reduces supply current to 1µA (max), further conserving power when the reference is not in use. Its robust design includes short-circuit protection and thermal shutdown, providing reliable performance in a variety of challenging conditions.

In summary, the MAX6126BASA41+T is a top-tier voltage reference that combines high accuracy, low noise, and low power consumption, making it an excellent choice for engineers looking to enhance the performance of their high-precision electronic systems.
