Overview
The ADR821BRMZ-R2 is a precision voltage reference and operational amplifier integrated into a 10-lead MSOP package. It provides a 2.5 V output with ±0.2% initial accuracy and a maximum temperature coefficient of 15 ppm/°C. The device operates from 2.8 V to 15 V, drawing 400 μA supply current. The op amp 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 operational amplifier in a compact 10-lead MSOP package
- Features on-board precision resistors for flexible gain configuration without external components
- Operates over an extended industrial temperature range from -40°C to +125°C
- Provides low power consumption with a total supply current of less than 400 μA
Applications
- Battery-powered instrumentation
- Portable medical instrumentation
- Data acquisition systems
- Industrial process controls
- Automotive applications
Procurement Notes
Verify the specific ordering suffix R2 indicates a 250-unit tube packaging format as per the manufacturer's ordering guide. Confirm RoHS compliance status through official documentation before integration. Ensure the selected grade meets the required initial accuracy and temperature drift specifications for the target application environment.
Selection Notes
Select this component when a combined reference and amplifier solution is required to minimize board space and component count. The B-grade variant offers tighter accuracy and drift compared to the A-grade. Consider the internal resistor matching and tolerance if configuring the amplifier for specific gain requirements using the onboard components.
Part Context
This part belongs to the ADR821/ADR827 family, which integrates a precision reference with a general-purpose op amp. The ADR821 variant specifically provides a 2.5 V reference output, whereas the ADR827 provides 1.25 V. Both share identical amplifier characteristics and packaging options within the same product line.
Replacement Considerations
Direct substitutes include the ADR821ARMZ for lower accuracy requirements or the ADR827BRMZ for a 1.25 V reference output. Verify pin compatibility and thermal resistance specifications when transitioning between these variants.
