MAX6133AASA41+

Overview

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

Feature Summary

• Utilizes bandgap technology for low-noise performance and excellent accuracy
• Features laser-trimmed thin-film resistors and post-package trimming
• Offers low dropout voltage and virtually independent supply current
• Provides stable operation with capacitive loads up to 100µF

Applications

• Precision regulators
• A/D and D/A converters
• Power supplies
• High-accuracy industrial and process control systems
• Hand-held instruments

Procurement Notes

Verify the specific suffix '41' corresponds to the required 4.096V output option when ordering. Confirm that the 8-pin SO package variant meets the thermal and mechanical requirements for the target application. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable device startup under all operating conditions.

Selection Notes

Select this part for applications requiring high precision and low power consumption. The 3ppm/°C temperature coefficient makes it suitable for wide temperature ranges. Consider the 15mA source current capability for driving moderate loads directly. Verify that the 0.1µF minimum output capacitance requirement fits within the system's stability constraints.

Part Context

This component belongs to the MAX6133 family of low-power, low-dropout voltage references. The family includes variants with different output voltages and packages, such as µMAX. The A-grade designation indicates tighter accuracy specifications compared to B-grade options. The series-mode design distinguishes it from shunt references by saving system power and minimizing external components.

Replacement Considerations

Direct substitutes include other MAX6133AASA41+ units or equivalent parts from the same manufacturer family with matching voltage and accuracy grades. Cross-referencing with similar series references requires verifying identical pinouts, output voltage, and temperature coefficients.
