Overview
The MAX6008AESA+ is an ultra-low-power shunt voltage reference with a nominal output of +2.5V, housed in an 8-pin SO package. It features an initial accuracy of 0.2% and a maximum temperature coefficient of 30ppm/°C over the -40°C to +85°C range. The device operates within a current range of 1µA to 2mA, ensuring stable performance in space-critical applications.
Feature Summary
- Ultra-low operating current guaranteed below 1µA
- High precision with 0.2% initial voltage accuracy
- Low temperature coefficient of 30ppm/°C max
- Factory-trimmed output voltages for immediate use
Applications
- Battery-powered equipment
- Portable meters
- Precision regulators
- A/D and D/A converters
Procurement Notes
Verify the specific suffix 'SA' confirms the 8-pin Small Outline package rather than the SOT23 variant. Ensure the '+A' designation matches the required 0.2% accuracy grade. Confirm RoHS compliance status via the '+' suffix. Cross-reference the full part number against the manufacturer's latest ordering guide to ensure availability and correct pinout configuration for your PCB layout.
Selection Notes
Select this component when low power consumption is critical alongside high precision. The 8-pin SO package offers a larger footprint than SOT23, potentially aiding thermal dissipation or manual assembly. Compare against LM285 or LT1004 if legacy compatibility is needed. Consider the AEC-Q100 qualification only if automotive variants are available in the desired package.
Part Context
This device belongs to the MAX6006–MAX6009 family of precision shunt references. It serves as a direct upgrade to older references like the LM285, offering lower power consumption and better stability. The family provides multiple voltage options, with the MAX6008 specifically targeting the common 2.5V requirement for data acquisition systems.
Replacement Considerations
Officially documented substitutes include the MAX6008AEUR+ (SOT23 package) and MAX6008BEESA+ (lower accuracy grade). Legacy replacements mentioned are the LM285 and LT1004, though these may require circuit adjustments due to higher current requirements.
