Maxim Integrated MAX6145ESA Precision Voltage Reference

The MAX6145ESA from Maxim Integrated is a high-precision, low-noise, series voltage reference designed to ensure stability and accuracy in a broad range of applications. This device is particularly suitable for high-end instrumentation, A/D and D/D converters, and industrial automation systems where consistent and reliable voltage reference is crucial.

Encased in a compact 8-pin NSOIC package, the MAX6145ESA provides a fixed output voltage of 4.096V, which is a common reference voltage for 12-bit and 16-bit converters. This voltage reference boasts an impressive initial accuracy of ±0.02% and a low temperature coefficient of 3ppm/°C (max), ensuring that the output voltage remains stable over a wide temperature range (-40°C to +85°C).

One of the standout features of the MAX6145ESA is its low dropout voltage, which allows it to maintain accurate output even with minimal input-to-output differential. This makes it particularly useful in low-headroom applications or when operating from batteries with diminishing charge.

The device also exhibits an excellent transient response, which helps maintain voltage stability during sudden changes in load. Furthermore, it offers a low output noise of 1.5µVp-p (0.1Hz to 10Hz), making it an ideal choice for sensitive analog circuits where noise can significantly impact performance.

For added flexibility, the MAX6145ESA includes a force-sense configuration that corrects line and load regulation errors. It has the capability to source or sink up to 10mA of output current, and its quiescent current is modest, typically 940µA, which is beneficial for power-sensitive applications.

Maxim Integrated's commitment to quality is evident in the MAX6145ESA's robust design, which includes short-circuit protection and thermal shutdown features. These protections ensure the longevity and reliability of the device even under adverse conditions.

In summary, the MAX6145ESA from Maxim Integrated is a versatile and dependable voltage reference that offers precision, low noise, and high stability, making it an ideal choice for engineers and designers looking to enhance the performance of their electronic systems.
