AD780AR-REEL7

Overview

The AD780AR-REEL7 is a precision series voltage reference integrated circuit manufactured by Analog Devices Inc. It provides stable output voltages of 2.5 V or 3 V with an initial accuracy of 0.04% and a temperature coefficient of 7 PPM/°C. The device operates within an extended industrial temperature range from -55°C to +125°C and supports a maximum shunt current of 10 mA. It features a maximum input voltage of 36 V and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with low temperature drift for stable reference performance
• Supports wide input voltage ranges up to 36 V for flexible power supply integration
• Operates reliably across extended industrial temperature environments

Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution data acquisition systems requiring stable voltage baselines
• Industrial instrumentation circuits demanding long-term stability

Procurement Notes

Verify the specific suffix configuration against official documentation, as variations may indicate different packaging or environmental ratings. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure the component meets RoHS compliance requirements for your target market before finalizing procurement orders.

Selection Notes

Select this component when applications require a fixed series reference with tight initial accuracy and moderate temperature stability. Compare against lower-drift alternatives if extreme thermal precision is necessary. Verify that the SOIC-8 package footprint aligns with the printed circuit board design constraints and thermal management requirements.

Part Context

This part belongs to the AD780 family of ultrahigh precision bandgap references. The REEL7 suffix indicates tape-and-reel packaging suitable for automated assembly processes. The AR designation typically denotes the industrial temperature grade variant within the product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer portfolio. Verify that alternative parts match the 2.5 V or 3 V output options and similar accuracy specifications.
