Overview
The TS3330AMR is a micropower high precision series voltage reference manufactured by STMicroelectronics. It provides a fixed output voltage of 3 V with an initial accuracy of 0.15%. The device operates within a temperature range of -40°C to +125°C and features a maximum input voltage of 5.5 V. Typical operating supply current is 3.9 µA, with a maximum of 10 µA. The maximum shunt current is 5 mA, and the temperature coefficient is 30 PPM/°C. It is housed in a QFN-8 surface-mount package.
Feature Summary
- Micropower operation with low typical supply current for energy efficiency
- High precision series voltage reference design ensuring stable output
- Wide industrial temperature range capability for robust performance
Applications
- Precision analog-to-digital converter (ADC) reference sources
- Data acquisition systems requiring stable voltage benchmarks
- Battery-powered instrumentation utilizing low power consumption
Procurement Notes
Verify the specific suffix 'AMR' corresponds to the required reel packaging configuration from official STMicroelectronics documentation. Confirm that the QFN-8 package dimensions and pinout match the target PCB footprint. Ensure the thermal requirements align with the specified operating temperature range during system integration.
Selection Notes
Select this component when a fixed 3 V reference with high initial accuracy is required. Consider the low quiescent current for battery-operated applications. Verify that the input voltage does not exceed the 5.5 V maximum limit. Check if the QFN-8 package is suitable for the assembly process compared to other available packages in the TS3330 series.
Part Context
The TS3330AMR belongs to the TS33 series of micropower high precision series voltage references from STMicroelectronics. This family is designed for applications demanding low power consumption alongside high accuracy. The AMR suffix typically indicates a specific tape and reel packaging format intended for automated surface-mount assembly processes.
Replacement Considerations
Consult official STMicroelectronics documentation for confirmed substitute part numbers within the TS33 series or equivalent products from other manufacturers. Verify electrical parameter compatibility before substitution.
