MAX6133AASA41+T

Overview

The MAX6133AASA41+T is a high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.04% and a maximum temperature coefficient of 3ppm/°C. The device operates within a supply voltage range of 2.7V to 12.6V, drawing a typical quiescent current of 40µA. It supports a source current up to 15mA and features a low dropout voltage of 200mV (max). The component is housed in an 8-pin SO package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Utilizes bandgap technology with laser-trimmed thin-film resistors for high stability and precision.
• Features ultra-low quiescent current consumption that remains virtually independent of the supply voltage.
• Provides excellent line and load regulation specifications to maintain output stability under varying conditions.

Applications

• Precision regulators
• A/D and D/A converters
• Power supplies

Procurement Notes

Verify the specific suffix '41' confirms the 4.096V output option when sourcing this part. Confirm the 'SO' designation matches the required 8-pin surface-mount package type. Ensure the 'A' grade selection aligns with the necessary ±0.04% accuracy requirements for the target design. Check RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a fixed 4.096V reference is required with minimal external components. The low power consumption makes it suitable for battery-operated systems where efficiency is critical. The wide input voltage range allows flexibility in system power architecture without requiring additional regulation stages before the reference.

Part Context

This part belongs to the MAX6133 family of low-power, low-dropout voltage references. The family includes various output voltages and packages, such as µMAX and SO. The A-grade variants offer tighter accuracy specifications compared to B-grade options. The MAX6133 series is designed for applications demanding high precision in compact form factors.

Replacement Considerations

Direct substitutes include other MAX6133 variants with different output voltages or packages, provided the electrical parameters meet the circuit requirements. Verify pin compatibility and thermal characteristics when replacing with similar series references from the manufacturer.
