Overview
The MAX6133AASA30+T is a high-precision, low-power series voltage reference featuring a maximum temperature coefficient of 3ppm/°C and a dropout voltage of 200mV. It delivers a fixed 3.000V output with an initial accuracy of ±0.04%. The device operates within a supply voltage range of 3.2V to 12.6V and consumes a typical quiescent current of 40µA. It supports source currents up to 15mA and includes line regulation of 30µV/V and load regulation of 0.06mV/mA. 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 with laser-trimmed thin-film resistors for high stability
- Provides excellent precision performance suitable for portable applications
- Features low dropout voltage allowing operation with minimal input-output differential
- Consumes minimal external components compared to shunt references
Applications
- Precision regulators
- A/D and D/A converters
- High-accuracy industrial and process control systems
- Hand-held instruments
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube configuration. Confirm the 'A' grade designation matches the required 3ppm/°C temperature coefficient and 0.04% accuracy specifications. Ensure the manufacturer is identified as Analog Devices or Maxim Integrated to guarantee authenticity and datasheet alignment.
Selection Notes
Select this part when a fixed 3V reference is required with ultra-low drift over wide temperature ranges. The low quiescent current makes it suitable for battery-powered designs. Verify that the input voltage remains above the minimum specified level to maintain regulation. Consider the 8-pin SO package dimensions for PCB layout constraints.
Part Context
This component belongs to the MAX6133 family of high-precision voltage references. It shares architectural similarities with other members like the MAX6133AASA50 but differs in output voltage and specific grading. The series-mode design distinguishes it from shunt references by offering higher efficiency and lower power consumption.
Replacement Considerations
Direct substitutes include other MAX6133 variants such as MAX6133AASA50 for different voltage requirements. Cross-family replacements may require verification of pin compatibility and thermal characteristics.
