Maxim Integrated MAX6198AESA Precision Voltage Reference

The MAX6198AESA from Maxim Integrated is a high-precision voltage reference chip that provides a stable and accurate reference voltage for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision circuit applications. This component is designed to ensure reliability and performance in systems where voltage accuracy is critical.

The MAX6198AESA offers a fixed output voltage of 4.096V with an impressive initial accuracy of ±0.02%. This tight accuracy is maintained over the full operating temperature range of -40°C to +85°C, making it suitable for a wide range of environments and applications. Additionally, the component boasts an excellent low temperature coefficient of typically 3ppm/°C, ensuring minimal deviation in output voltage with temperature variations.

With a low dropout voltage and a quiescent current of typically 350µA, the MAX6198AESA is energy-efficient, making it ideal for battery-powered devices and portable applications. Its low dropout voltage allows it to maintain a stable output even when the supply voltage is close to the output voltage, which is particularly useful in low-voltage operations.

The device is offered in a small 8-pin SOIC package, which is space-saving and convenient for compact circuit designs. The MAX6198AESA also features a force-sense connection that compensates for the voltage drop due to the load, ensuring that the reference voltage remains accurate at the point of load.

Moreover, the MAX6198AESA includes a trim input that allows fine adjustment of the output voltage, providing additional flexibility for calibration in precision applications. This feature can be used to compensate for system errors or to calibrate the voltage reference to a specific value as required by the application.

Overall, the MAX6198AESA from Maxim Integrated is a robust and precise voltage reference component, designed to deliver consistent performance for systems requiring high accuracy and stability in their reference voltages.
