Maxim Integrated MAX876AESA+ Voltage Reference

The MAX876AESA+ from Maxim Integrated is a precision, low-power, low-dropout voltage reference. This device is part of a series of voltage references that offer high stability and low temperature coefficient, making it an ideal choice for high-performance analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-accuracy applications.

With a typical output voltage of 5V, the MAX876AESA+ is designed to maintain a high level of accuracy with a deviation of ±0.15% over the entire operating temperature range. This ensures reliable performance even under varying conditions. Additionally, the device boasts an impressive temperature coefficient of just 20ppm/°C max, which contributes to its overall stability and precision.

The MAX876AESA+ operates with a supply voltage range from 4.75V to 12.6V, providing designers with flexibility in system power design. The low dropout voltage allows the reference to continue operating even when the supply voltage is very close to the output voltage, which is particularly beneficial in battery-powered applications where power efficiency is crucial.

Another key feature of the MAX876AESA+ is its low quiescent current, which typically stands at 180µA. This low power consumption makes it suitable for portable and battery-operated equipment, where extending the battery life is of paramount importance. Furthermore, the device is provided in a small 8-pin SOIC package, which is ideal for space-constrained applications.

The MAX876AESA+ also includes a force-sense connection that corrects for any voltage drops due to the resistance of the PCB traces, ensuring the accuracy of the voltage delivered to the load. This feature is particularly useful in precision applications where voltage drops can significantly affect performance.

Overall, the MAX876AESA+ from Maxim Integrated is a reliable and precise voltage reference that offers excellent stability, low power consumption, and a small footprint, making it an excellent choice for a wide range of high-accuracy electronic applications.
