MAX6195AESA+T

Overview

The MAX6195AESA+T is a precision, micropower, low-dropout series-mode voltage reference manufactured by Analog Devices / Maxim Integrated. It provides a nominal output voltage of 5.000V with an initial accuracy of ±5mV and a maximum temperature coefficient of 5ppm/°C. The device operates within a supply voltage range of VOUT + 0.2V to 12.6V and draws a maximum quiescent supply current of 35µA. It supports source and sink currents up to 500µA while maintaining stability with capacitive loads up to 2.2nF. The component is housed in an 8-pin SO package and functions reliably across a temperature range of -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 allows stable operation 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
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'A' corresponds to the required ±5mV initial accuracy grade against the official selector guide. Confirm the '+T' designation indicates tape-and-reel packaging if applicable to your assembly process. Ensure the ordering code matches the exact output voltage and tolerance specifications required for your circuit design before finalizing procurement.

Selection Notes

Select this component when a precise 5V reference is needed with minimal power consumption. The low dropout characteristic makes it suitable for battery-powered applications where input voltage may approach the output level. Verify that the load requirements do not exceed the 500µA sourcing or sinking limits to maintain guaranteed line and load regulation performance.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. The family shares common architectural features including micropower operation and low dropout capabilities. Variations within the family are distinguished primarily by their fixed output voltage levels and initial accuracy grades, allowing designers to choose the specific voltage and tolerance combination best suited for their system requirements.

Replacement Considerations

Direct replacements within the same family include MAX6195BESA+T (±2mV accuracy) and MAX6195CESA+T (±10mV accuracy). These parts share identical pinouts and electrical characteristics except for the initial accuracy specification.
