MAX6176BASA+T

Overview

The MAX6176BASA+T is a high-precision voltage reference providing a fixed +10V output. It features a maximum temperature coefficient of 3ppm/°C and an initial accuracy of ±0.05%. The device accepts input voltages from (VOUT + 2V) up to +40V, draws a typical supply current of 340μA, and can source up to 30mA or sink 2mA. It includes a TRIM pin for fine adjustment and a TEMP pin for die temperature sensing.

Feature Summary

• Proprietary curvature-correction circuit with laser-trimmed thin-film resistors ensures low drift and high precision.
• Integrated linear temperature transducer output proportional to the internal die temperature.
• Capable of sourcing 30mA and sinking 2mA without requiring external output bypass capacitors for stability.
• Output voltage can be finely adjusted using a resistive divider network connected to the dedicated TRIM pin.

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• Automotive sensor interfaces
• Precision digital voltmeters

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the operating environment remains within the specified -40°C to +125°C range to maintain guaranteed performance parameters.

Selection Notes

Select this component when a stable +10V reference is required alongside integrated temperature monitoring capabilities. The wide input voltage range accommodates various supply rails, while the low quiescent current supports battery-operated designs. Verify that the load requirements do not exceed the specified sourcing and sinking limits.

Part Context

This part belongs to the MAX6173–MAX6177 family of high-precision voltage references. All members share identical architectures featuring curvature correction and temperature sensing, differing primarily in their factory-preset output voltages ranging from +2.5V to +10V.

Replacement Considerations

Other members of the MAX6173–MAX6177 series may serve as functional substitutes if the specific output voltage requirement differs. Verify that any alternative maintains the necessary accuracy, temperature coefficient, and thermal performance specifications.

FAQ

Does the MAX6176BASA+T require an output capacitor for stability?

No, the device does not require an output bypass capacitor for stability and remains stable with capacitive loads up to 100μF.

How is the output voltage trimmed on this device?

The output voltage is trimmed by connecting a resistive divider network between the OUT, TRIM, and GND pins.
