AD8031BR-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8031BR-REEL is a single-channel, voltage feedback operational amplifier manufactured by Analog Devices Inc. It operates on supply voltages ranging from +2.7 V to +12 V (single) or ±1.35 V to ±6 V (dual). Key electrical parameters include an 80 MHz small-signal bandwidth at unity gain, a 30 V/µs slew rate, and a quiescent current of 800 µA per amplifier. The device features rail-to-rail input and output capabilities, with an input common-mode range extending 200 mV beyond the rails and no phase reversal up to 500 mV beyond supplies.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output architecture maximizing dynamic range
• High-speed performance with 80 MHz bandwidth and fast settling time
• Low power consumption suitable for battery-operated systems
• Extended linear input range without phase reversal

Instrumentation, Op Amps, Buffer Amps Applications

• High speed, battery-operated systems
• Portable test instruments
• A/D buffers
• Active filters
• High speed, set-and-demand amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix REEL indicates tape and reel packaging rather than tube packaging when sourcing components. Confirm the BR grade specifications against the official datasheet to ensure compliance with required offset voltage and bias current limits. Check manufacturer documentation for any specific handling requirements related to the BiCOM process technology used in fabrication.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high bandwidth and low power dissipation in single-supply environments. The rail-to-rail I/O capability makes it suitable for driving ADCs directly. Ensure the design accounts for the output swing limitations under heavy load conditions. Consider the thermal characteristics if operating near maximum ambient temperatures or with significant power dissipation.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8031/AD8032 family of single-supply, voltage feedback amplifiers. The AD8031 is the single-channel version, while the AD8032 is the dual-channel variant. Both utilize Analog Devices' XFCB process technology to achieve high speed and low power simultaneously. The BR grade represents a standard performance option within the product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8031ARZ-REEL7 is a verified substitute offering identical electrical performance but packaged in an SOIC-8 format instead of SOT-23.
