ADR827ARMZ-REEL7

Overview

The ADR827ARMZ-REEL7 is a low-power precision reference and operational amplifier integrated in a 10-lead MSOP package. It provides a fixed 1.25 V output with ±0.4% initial accuracy and a maximum temperature coefficient of 30 ppm/°C. The device operates from 2.7 V to 15 V, drawing 400 μA supply current. The amplifier supports single or dual supplies up to ±15 V, featuring rail-to-rail input/output, 500 μV maximum offset voltage, and 50 nA bias current.

Feature Summary

• Combines a precision voltage reference and an op amp in a compact 10-lead MSOP package
• Features on-board precision resistors for flexible circuit configurations
• Operates independently as a low-noise reference or a unity-gain stable amplifier

Applications

• Battery-powered instrumentation
• Portable medical instrumentation
• Data acquisition systems
• Industrial process controls
• Automotive applications

Procurement Notes

Verify the specific suffix (e.g., REEL7) matches the required packaging format. Confirm the 'A' grade designation corresponds to the necessary ±0.4% accuracy and 30 ppm/°C drift specifications. Ensure the 10-lead MSOP footprint aligns with the PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a combined reference and amplifier solution is needed to minimize board space and power consumption. The ADR827 is suitable for designs requiring a 1.25 V reference level. Consider the B-grade variant if tighter accuracy and lower drift are required. Verify that the 2.7 V minimum operating voltage meets the system's supply constraints.

Part Context

This part belongs to the ADR821/ADR827 family, which integrates a precision reference and op amp. The ADR827 specifically offers a 1.25 V reference output, whereas the ADR821 provides 2.50 V. Both share identical amplifier characteristics and package options, differing primarily in the reference voltage and associated resistor network values.
