MAX6198AESA+

Overview

The MAX6198AESA+ is a precision, micropower, low-dropout voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±5mV and a maximum temperature coefficient of 5ppm/°C. The device operates within a supply voltage range of 4.296V to 12.6V and draws a maximum quiescent supply current of 35µA. It supports source and sink currents up to 500µA with a dropout voltage of 100mV at full load. 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 guarantees stability 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' confirms the ±5mV initial accuracy grade when sourcing this component. Confirm the 'E' indicates the SOIC-8 package type and the '+' denotes lead-free/RoHS compliance status. Ensure the operating environment stays within the specified -40°C to +85°C industrial temperature range to maintain guaranteed performance parameters.

Selection Notes

Select this part for applications requiring a stable 4.096V reference with minimal power consumption. The low quiescent current makes it suitable for battery-powered systems where efficiency is critical. Consider the internal compensation benefits if board space constraints prevent the use of external stabilization capacitors while maintaining transient response requirements.

Part Context

This component belongs to the MAX6190–MAX6195/MAX6198 family of precision bandgap references. All members share identical pinouts and core technologies but differ in fixed output voltages ranging from 1.25V to 5.0V. The MAX6198 specifically targets applications needing a 4.096V output level compatible with standard ADC/DAC reference inputs.

Replacement Considerations

Other members of the MAX619x family (e.g., MAX6190AESA+, MAX6195AESA+) are pin-compatible alternatives offering different fixed output voltages.
