MAX6195AESA+

Overview

The MAX6195AESA+ is a precision, micropower, low-dropout voltage reference providing a fixed 5.0V output in an 8-pin SO package. It features a maximum initial accuracy of ±2mV and a temperature coefficient of less than 5ppm/°C. The device draws a maximum quiescent supply current of 35µA and supports source and sink currents up to 500µA with a dropout voltage of approximately 100mV at full load. Operating over a -40°C to +85°C range, it maintains stability with capacitive loads up to 2.2nF.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high initial accuracy and very low temperature drift.
• Series-mode architecture provides supply current virtually immune to input voltage variations, maximizing efficiency for battery-powered applications.
• Internally compensated design eliminates the need for external compensation components while maintaining stability with significant capacitive loads.

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' corresponds to the required ±2mV initial accuracy grade, as other grades exist within the MAX6195 family. Confirm the 'ESA+' designation indicates the lead-free/RoHS-compliant 8-SO package variant. Ensure the input voltage source can provide transient currents exceeding nominal levels during turn-on to guarantee reliable operation.

Selection Notes

Select this component when a stable 5.0V reference is required with minimal power consumption. The series-mode topology is preferred over shunt references for improved efficiency where load current varies. Verify that the application's input voltage remains above the minimum dropout threshold to maintain regulation under all expected load conditions.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision bandgap 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 initial accuracy grades.

Replacement Considerations

Other members of the MAX619x family (e.g., MAX6194, MAX6198) offer similar electrical characteristics but with different fixed output voltages. Substitution requires matching the required reference voltage level alongside the accuracy and package constraints.
