MAX6126B50

Overview

The MAX6126B50 is a series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 5.0V with an initial accuracy tolerance of ±0.1%. The device operates within an input voltage range of 4.3V to 12.6V and delivers a maximum output current of 10 mA while consuming a supply current of 725µA. It features a temperature coefficient of 7ppm/°C and low noise performance of 2.4µVp-p from 0.1Hz to 10Hz. The component is housed in an 8-uMAX/uSOP surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Ultra-high precision with ±0.1% initial accuracy for critical measurement applications
• Ultra-low noise characteristics ensuring signal integrity in sensitive analog circuits
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• High-resolution data acquisition systems
• Precision instrumentation amplifiers
• Calibration equipment requiring stable reference voltages

Procurement Notes

Verify the specific suffix and package type against official datasheets, as availability may vary. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices. Ensure the selected variant matches the required output voltage and accuracy grade for your specific design constraints before ordering.

Selection Notes

Select this component when a stable 5.0V reference with high precision is required. Compare the 7ppm/°C temperature coefficient against application thermal requirements. Consider the 10mA output capability for driving loads without external buffering. Evaluate the 8-uMAX/uSOP footprint against PCB layout constraints.

Part Context

Part of the MAX6126 family of ultra-high-precision, ultra-low-noise series voltage references. This family offers various fixed output voltages and accuracy grades (A/B/C) packaged in compact forms like uMAX and SOIC. Designed for demanding analog applications where stability and low noise are paramount.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6126 series such as MAX6126A50+ for tighter accuracy or MAX6126C50+ for cost-sensitive options. Verify that substitute parts meet the same 7ppm/°C tempco and 2.4µVp-p noise specifications.
