MAX6198CESA

Overview

The MAX6198CESA is a precision, micropower, low-dropout voltage reference with a fixed output of 4.096V. It features an initial accuracy of ±10mV and a maximum temperature coefficient of 25ppm/°C. The device draws a maximum quiescent supply current of 35µA and supports source/sink currents up to 500µA. It operates within a supply voltage range of 4.296V to 12.6V and maintains stability with capacitive loads up to 2.2nF.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high initial accuracy and low temperature drift.
• Micropower series-mode architecture provides virtually input-voltage-immune supply current for battery-powered efficiency.
• Internally compensated design guarantees fast settling times and stability with capacitive loads up to 2.2nF.

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 'CESA' corresponds to the required ±10mV accuracy and 25ppm/°C temperature coefficient grade. Confirm the package type matches the 8-pin SO footprint. Ensure the application supply voltage remains above the minimum dropout threshold relative to the 4.096V output to maintain regulation.

Selection Notes

Select this component when a stable 4.096V reference is needed with moderate precision requirements. It is suitable for applications where board space is limited due to optional output capacitance. Consider the 35µA quiescent current for power-sensitive designs compared to shunt references.

Part Context

Part of the MAX6190–MAX6195/MAX6198 family of precision bandgap references. Manufactured using BiCMOS process technology by Maxim Integrated (now Analog Devices). Designed for industrial and commercial environments with an operating temperature range of -40°C to +85°C.

Replacement Considerations

Cross-reference with other MAX6198 variants such as MAX6198AESA+ or MAX6198BESA+ if tighter accuracy or lower temperature coefficients are required. Verify pin compatibility for direct replacement in existing 8-SO layouts.
