Overview
The MAX6143AASA10+ is a high-precision series voltage reference providing a fixed +10V output with ±0.05% initial accuracy and a maximum temperature coefficient of 3ppm/°C. It accepts input voltages from VOUT + 2V up to +40V, drawing 340µA typical supply current. The device features an active-low shutdown pin reducing current to 0.01µA, a TRIM input for fine adjustment, and a TEMP output proportional to die temperature. It operates over -40°C to +125°C in an 8-pin SO package without requiring output bypass capacitors.
Feature Summary
- Integrated linear temperature transducer output
- Active-low shutdown capability
- Output voltage trimming via resistive divider
- Capacitive load stability
Applications
- High-resolution A/D converters
- D/A converters
- Threshold detectors
- Digital voltmeters
Procurement Notes
Verify the specific suffix 'A' indicates the 0.05% accuracy grade and 'S' denotes the SOIC package. Confirm the '+' suffix ensures RoHS compliance. Cross-reference the manufacturer part number against official Analog Devices or Maxim Integrated documentation to ensure authenticity and correct revision status before procurement.
Selection Notes
Select this component when a stable 10V reference is required alongside integrated temperature sensing capabilities. The low quiescent current and shutdown feature make it suitable for battery-powered systems. Ensure the input voltage range accommodates the dropout requirements relative to the 10V output under varying load conditions.
Part Context
This device belongs to the MAX6143 family of high-precision voltage references. Variants within the family offer different preset output voltages including 2.5V, 3.3V, 4.096V, and 5.0V. The 'A' grade signifies tighter initial accuracy compared to the 'B' grade, while all variants share the same core architecture and package options.
Replacement Considerations
Direct substitutes include other MAX6143AASA variants with different output voltages if the 10V requirement can be adjusted. Verify pin compatibility and thermal characteristics when considering cross-family replacements.
