MAX6198AESA/V+T

Overview

The MAX6198AESA/V+T is a precision, micropower, low-dropout series-mode bandgap voltage reference. It provides a fixed output of 4.096V with an initial accuracy of ±5mV and a maximum temperature coefficient of 5ppm/°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 features internal compensation for stability with capacitive loads up to 2.2nF.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high initial accuracy and very low temperature drift.
• Micropower architecture maintains virtually constant supply current regardless of input voltage variations, optimizing efficiency in battery-powered systems.
• Internally compensated design eliminates the need for external capacitors for frequency stability while supporting fast settling times.

Applications

• Hand-Held Instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control

Procurement Notes

Verify that the specific suffix /V indicates automotive qualification status as defined by the manufacturer's ordering guide. Confirm the package type matches the required footprint, as the datasheet specifies an 8-pin SOIC configuration. Ensure the component meets lead-free/RoHS compliance requirements if applicable to the assembly process.

Selection Notes

Select this part when a stable 4.096V reference is required with minimal power consumption. The low dropout characteristic allows operation at input voltages close to the output level. Consider the 500µA load capability for driving ADCs or DACs directly without additional buffering stages.

Part Context

This component belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. All members share identical pinouts and core architectures but differ in nominal output voltages ranging from 1.25V to 5.0V. The MAX6198 specifically targets applications requiring a 4.096V reference standard.

Replacement Considerations

Other members of the MAX619x family (e.g., MAX6190 through MAX6195) are pin-compatible alternatives offering different fixed output voltages. Verify that the required reference voltage matches the application needs before substituting.
