MAX6192BESA+T

Overview

The MAX6192BESA+T 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, drawing a maximum quiescent current of 35µA. It features a dropout voltage of 100mV at a 500µA load current and supports source/sink currents up to 500µA. Packaged in an 8-pin SOIC, it is stable with capacitive loads up to 2.2nF.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers extremely low power consumption suitable for battery-powered instruments.
• Capable of sourcing and sinking up to 500µA with minimal dropout voltage.
• Internally compensated for fast settling times without requiring external compensation 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 that the ordering suffix matches the required specifications, as variations exist for automotive qualification (e.g., /V) or different accuracy grades. Confirm package type and RoHS compliance status. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable operation.

Selection Notes

Select this component when a fixed 2.5V reference with high initial accuracy and low temperature drift is required. Consider the MAX6192BESA+T over shunt references for improved efficiency in battery applications due to its series-mode architecture. Evaluate the specific accuracy grade (A, B, or C) based on the system's tolerance requirements.

Part Context

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

Replacement Considerations

Direct substitutes within the same family include MAX6192AESA+T (±2mV accuracy) and MAX6192CESA+T (±10mV accuracy). Verify pin compatibility and electrical parameter alignment before substitution.

FAQ
