MAX6192BESA+

Overview

The MAX6192BESA+ is a precision, micropower, low-dropout series-mode voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±5mV and a maximum temperature coefficient of <10ppm/°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 guarantees load regulation of 0.14µV/µA and line regulation of 15µV/V. The component is housed in an 8-pin SO package and supports source and sink currents up to 500µA.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Features internally compensated design ensuring stability with capacitive loads up to 2.2nF
• Offers virtually input-voltage-immune supply current for optimized battery-powered efficiency

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 'ES' corresponds to the standard 8-pin SO package configuration before procurement. Confirm that the '+T' or '+' designation aligns with lead-free/RoHS compliance requirements for your assembly process. Ensure the input voltage source can provide transient currents during turn-on if operating near minimum dropout conditions. Cross-reference the exact part number against the manufacturer's latest ordering guide to confirm availability status.

Selection Notes

Select this component when a fixed 2.5V reference is required with tight initial accuracy specifications. It is suitable for applications where board space is critical due to the lack of mandatory external compensation capacitors. Consider this device for systems requiring both sourcing and sinking capabilities up to 500µA. Evaluate the low quiescent current benefit for extending battery life in portable instrumentation compared to shunt-mode references.

Part Context

This component belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. The family shares common architectural features including micropower operation and low-dropout characteristics. Variants within the family differ primarily in their fixed output voltage levels and specific accuracy grades (A, B, C). The MAX6192 specifically targets the 2.5V output requirement within this lineup.

Replacement Considerations

Direct substitutes within the same family include MAX6192AESA+ (±2mV accuracy) and MAX6192CESA+ (±6mV accuracy), provided the accuracy grade meets system requirements. Other family members like MAX6190 or MAX6191 offer different voltages but share similar electrical characteristics.
