Product details
Overview
MAX6043BAUT10-T from Maxim Integrated is a precision +10.0V voltage reference IC using bandgap technology, delivering 0.1% initial accuracy, 20ppm/°C max temperature coefficient, and 320µA quiescent current in a 6-pin SOT23 package. It operates from +12V to +40V input and supports sourcing up to 10mA, making it suitable for high-resolution 16-bit ADCs in automotive sensor signal conditioning.
For engineers reviewing the MAX6043BAUT10-T datasheet, MAX6043BAUT10-T pinout, MAX6043BAUT10-T application, or MAX6043BAUT10-T equivalent, key selection criteria include its 10V output stability over -40°C to +125°C, no-output-capacitor-required operation, low 19µVP-P (0.1Hz–10Hz) noise, and compatibility with capacitive loads up to 100µF.
Technical Context
The MAX6043BAUT10-T employs curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve tight initial tolerance and low thermal drift. Its dual-output architecture (OUTF/OUTS) enables Kelvin sensing for improved load regulation accuracy under varying PCB trace resistance.
It features internal short-circuit protection limiting output current to ±60mA, operates without external bypass capacitors, and maintains stability across full 0–100µF capacitive load range - eliminating layout constraints common in space-constrained automotive and industrial modules.

FAQ
What is the output voltage tolerance of the MAX6043BAUT10-T at +25°C?
The MAX6043BAUT10-T has an initial output voltage tolerance of ±0.1% at +25°C, corresponding to +9.990V to +10.010V. This specification is guaranteed across 100% production testing and reflects laser-trimmed thin-film resistor matching within the bandgap core of the MAX6043BAUT10-T.
Does the MAX6043BAUT10-T require an output bypass capacitor for stability?
No, the MAX6043BAUT10-T does not require an external output capacitor for stability. It remains stable with capacitive loads ranging from 0 to 100µF, including ceramic, tantalum, and electrolytic types. This eliminates board area and BOM cost associated with output filtering - a key design advantage of the MAX6043BAUT10-T.
What is the maximum load current the MAX6043BAUT10-T can source or sink?
The MAX6043BAUT10-T can source up to +10mA and sink up to –0.6mA while maintaining specified accuracy. Output short-circuit current is internally limited to ±60mA, protecting the MAX6043BAUT10-T during fault conditions such as accidental grounding of the reference output.
How does the Kelvin OUTF/OUTS configuration improve accuracy in the MAX6043BAUT10-T?
The MAX6043BAUT10-T's OUTF (force) and OUTS (sense) pins form a Kelvin connection that separates current-carrying and voltage-sensing paths. This eliminates errors caused by voltage drop across PCB traces or connectors, enabling true load-regulation immunity - a critical feature for the MAX6043BAUT10-T in high-precision measurement systems.
Is the MAX6043BAUT10-T qualified for automotive applications?
Yes, the MAX6043BAUT10-T is rated for the automotive temperature range of –40°C to +125°C and meets AEC-Q100 Grade 1 requirements. Its 20ppm/°C max temperature coefficient, robust ESD performance, and short-circuit protection make it suitable for under-hood and chassis-mounted automotive electronics - a defining characteristic of the MAX6043BAUT10-T.
