Maxim Integrated MAX6141ESA Precision Voltage Reference

The MAX6141ESA from Maxim Integrated is a high-precision voltage reference component designed to offer a stable and accurate reference voltage for various applications. This device is part of Maxim's series of low-dropout, micropower, three-terminal voltage references that provide a fixed voltage output from an unregulated input source. The MAX6141ESA is an essential building block in precision data conversion systems, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and various mixed-signal circuits.

Featuring a series reference architecture, the MAX6141ESA provides a 4.096V output voltage with an impressive initial accuracy of ±0.02%. It has an excellent temperature coefficient of just 3ppm/°C (typical), ensuring stable performance over a wide temperature range of -40°C to +85°C. This makes it suitable for demanding applications that require high stability and accuracy in environments with fluctuating temperatures.

With a low supply current of only 120µA (typical), this voltage reference is optimized for battery-powered and portable devices where power efficiency is crucial. Moreover, the MAX6141ESA can source or sink up to 5mA of output current, providing versatility in a broad range of load conditions. The low dropout voltage of merely 200mV (max) at full load allows for operation with minimal headroom above the output voltage, which is beneficial in low-voltage applications.

The MAX6141ESA is available in a compact 8-pin SOIC package, making it easy to integrate into space-constrained designs. Its no-load condition stability and low output noise of 15µVp-p (0.1Hz to 10Hz) contribute to its use in high-performance applications where noise sensitivity is critical, such as precision measurement instruments and industrial control systems.

Overall, the Maxim Integrated MAX6141ESA is a reliable and high-quality component for designers seeking a stable voltage reference with low power consumption, high accuracy, and minimal temperature drift. Its robust features make it an ideal choice for precision applications in medical, industrial, and portable electronics.
