MAX6192AESA+

Overview

The MAX6192AESA+ is a precision, micropower, low-dropout voltage reference from the MAX6190–MAX6195/MAX6198 family. It provides a fixed output voltage of 2.5V with an initial accuracy of ±5mV and a maximum temperature coefficient of 5ppm/°C. The device operates within a supply voltage range of 2.7V to 12.6V and draws a maximum quiescent supply current of 35µA. It features internal compensation for fast settling times and remains stable with capacitive loads up to 2.2nF. The component supports source and sink currents up to 500µA while maintaining specified load regulation.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve high initial accuracy and low temperature drift.
• Offers extremely low quiescent supply current that remains virtually independent of input voltage variations across the operating range.
• Internally compensated design ensures stability with capacitive loads up to 2.2nF without requiring external components for frequency stability.

Applications

• Hand-held instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'A' indicates the ±5mV initial accuracy grade when sourcing replacements. Confirm the package type matches the 8-pin SO specification required for your PCB footprint. Ensure the operating environment stays within the -40°C to +85°C industrial temperature range defined in the datasheet specifications.

Selection Notes

Select this component when a fixed 2.5V reference is required with tight initial accuracy tolerances. Consider the low dropout characteristic for applications where the input voltage is close to the output level. Evaluate the micropower consumption against battery life requirements compared to shunt-mode references.

Part Context

This part belongs to the Maxim Integrated MAX6190 series of precision voltage references. The family shares common architectural features including low power consumption and low dropout capabilities. Variations within the series differ primarily by output voltage levels and initial accuracy grades, allowing designers to choose specific performance tiers for different system requirements.

Replacement Considerations

Compatible substitutes include other parts from the MAX6190–MAX6195/MAX6198 family with matching 2.5V output and ±5mV accuracy, such as MAX6192BESA+ or MAX6192CESA+, provided pin compatibility and thermal characteristics are verified.
