Overview
The MAX6133A25+T is a high-precision, low-power series voltage reference featuring a maximum temperature coefficient of 5ppm/°C and an initial accuracy of ±0.06%. It delivers a fixed 2.5V output with a quiescent supply current of 40µA to 85µA across the -40°C to +125°C operating range. The device supports up to 15mA source current and operates within a 2.7V to 12.6V input voltage range. Packaged in an 8-pin µMAX format, it utilizes bandgap technology for low noise performance.
Feature Summary
- Low temperature coefficient ensures stable output across wide thermal ranges
- Ultra-low power consumption suitable for battery-operated systems
- High initial accuracy maintained through laser trimming and post-package calibration
- Compact surface-mount packaging designed for space-constrained applications
Applications
- Precision regulators
- A/D and D/A converters
- Hand-held instruments
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the 'A' grade designation aligns with the required 5ppm/°C temperature coefficient specification for µMAX packages. Ensure compatibility with the 8-pin µMAX footprint dimensions during PCB layout review.
Selection Notes
Select this component when system requirements demand minimal supply current alongside high precision. The µMAX package offers a smaller footprint compared to SOIC alternatives. Verify that the 2.5V output level matches the downstream circuitry reference needs without requiring external scaling resistors.
Part Context
This part belongs to the MAX6133 family of low-dropout voltage references manufactured by Analog Devices / Maxim Integrated. The family includes various output voltages and package options, with the A-grade devices offering tighter temperature coefficients than B-grade counterparts.
Replacement Considerations
Cross-reference with other MAX6133 variants such as MAX6133AASA25+T for SOIC package equivalents or MAX6133B-series parts if relaxed accuracy specifications are acceptable.
