MAX6192AESA

Overview

The MAX6192AESA+ is a precision, micropower, low-dropout voltage reference providing a nominal output of 2.5V. It operates within an input voltage range of 2.7V to 12.6V and draws a maximum quiescent supply current of 35µA. The device features a maximum initial accuracy of ±5mV and a temperature coefficient of less than 5ppm/°C. It is housed in an 8-pin SO package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Series-mode architecture ensures supply current remains virtually independent of input voltage variations.
• Internally compensated design guarantees stability with capacitive loads up to 2.2nF without external components.

Applications

• Hand-held instruments
• Analog-to-digital and digital-to-analog converters
• Industrial process control systems
• Precision 3V/5V systems

Procurement Notes

Verify the specific suffix (e.g., +) indicates RoHS compliance when sourcing. Confirm the package type matches the required footprint. Ensure the input voltage source can provide transient currents during turn-on if operating near minimum dropout limits. Check for automotive qualified variants if environmental conditions require extended reliability standards.

Selection Notes

Select this component for applications requiring low power consumption and high accuracy in battery-operated devices. The series-mode topology offers superior efficiency compared to shunt references by drawing load current only when needed. Verify that the required output voltage aligns with the available options in the MAX6190–MAX6195/MAX6198 family.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower operation and low dropout characteristics, differentiated primarily by their fixed output voltage levels and accuracy grades.

FAQ

Does the MAX6192AESA+ require an external capacitor for stability?

No, the device is internally compensated and stable with capacitive loads ranging from 0 to 2.2nF. An external capacitor is optional but recommended to reduce overshoot during load transients.

How does the supply current behave relative to input voltage changes?

The quiescent supply current is virtually immune to input voltage variations, changing by only 0.8µA/V across the specified operating range.
