ADR821ARMZ-REEL7

Overview

The ADR821ARMZ-REEL7 is a low-power precision reference and operational amplifier integrated in a 10-lead MSOP package. It features an internal 2.5 V voltage reference with ±0.4% initial accuracy and 30 ppm/°C temperature drift, alongside a rail-to-rail input/output op amp. The device operates from a single supply of 2.8 V to 15 V or dual supplies of ±2.8 V to ±15 V. Total supply current is less than 400 μA. The op amp offers a maximum offset voltage of 500 μV and a bias current of 50 nA.

Feature Summary

Combines a precision voltage reference and a rail-to-rail operational amplifier within a single compact package.
Includes on-board precision resistors for flexible circuit configuration.
Operates over an extended industrial temperature range of -40°C to +125°C.
Designed for ultra-low power consumption with total supply current under 400 μA.

Applications

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

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated by the 'Z' suffix in the part number. Ensure the operating voltage requirements align with the specified 2.8 V minimum for the ADR821 variant. Check thermal resistance specifications if high ambient temperatures are expected.

Selection Notes

Select this component when both a stable voltage reference and signal amplification are required in space-constrained designs. The ADR821 provides a fixed 2.5 V reference output, whereas the ADR827 provides 1.25 V. Consider the B-grade variants if tighter accuracy (±0.2%) and lower drift (15 ppm/°C) are necessary compared to the standard A-grade specifications.

Part Context

This part belongs to the ADR821/ADR827 family from Analog Devices, which integrates reference and amplifier functions. It is distinct from standalone references like the ADR4xx series or ADCs like the AD7818. The 10-lead MSOP package differentiates it from the 8-lead MSOP packages used by many other precision references in the manufacturer's portfolio.
