Overview
The MAX6126B30+ is a series-mode precision voltage reference from Analog Devices/Maxim Integrated, housed in an 8-pin uMAX package. It provides a fixed 3V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 12ppm/°C across the -40°C to +125°C automotive range. The device operates on a supply voltage up to 12.6V, draws a maximum quiescent current of 725µA, and supports sink/source currents up to 10mA.
Feature Summary
- Features curvature-correction circuitry and laser-trimmed thin-film resistors for high stability.
- Includes independent force (OUTF) and sense (OUTS) outputs for remote Kelvin sensing.
- Operates with dropout voltages as low as 200mV without requiring external resistors.
Applications
- High-Resolution A/D and D/A Converters
- ATE Equipment
- Precision Current Sources
Procurement Notes
Verify the specific suffix 'B30+' against the manufacturer's official ordering guide to confirm the exact grade, package type, and output voltage specifications. Ensure compatibility with the required operating temperature range and load regulation requirements before finalizing procurement.
Selection Notes
Select this component when a stable 3V reference is needed in a compact uMAX footprint. Consider the B-grade accuracy and higher temperature coefficient compared to A-grade variants if cost or availability dictates. Verify that the 10mA drive capability meets the application's load requirements.
Part Context
This part belongs to the MAX6126 family of ultra-low-noise, high-precision voltage references. The family offers various output voltages and packages, including SOIC and uMAX, designed for applications demanding low power consumption and high accuracy in industrial and automotive environments.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the MAX6126 series, such as the MAX6126A30+, which offers tighter accuracy and lower temperature coefficients but may differ in initial performance specifications.
FAQ
How does the noise reduction pin affect performance?
Adding a capacitor to the NR pin improves wideband noise and AC power-supply rejection, though it increases the turn-on settling time.
What is the purpose of the GNDS pin?
The GNDS pin provides a ground-sense connection to cancel voltage drops in the ground return line when using the Kelvin connection configuration.
