AD8031ANZ

Instrumentation, Op Amps, Buffer Amps Overview

The AD8031ANZ is a single-channel voltage feedback amplifier manufactured by Analog Devices Inc. It operates on supply voltages ranging from +2.7 V to +12 V, or dual supplies up to ±6 V. The device features an 80 MHz small signal bandwidth and a 30 V/µs slew rate at unity gain. It consumes approximately 800 µA of quiescent current per amplifier. The input common-mode voltage range extends beyond the power rails by 200 mV, and the output swings to within 20 mV of either rail under light loads. It is housed in an 8-pin PDIP package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capability with extended common-mode range
• High-speed performance with low power consumption
• No phase reversal when inputs exceed supply rails

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix ANZ indicates compliance with RoHS standards and lead-free manufacturing processes as defined by Analog Devices. Confirm that the 8-PDIP package dimensions match the required PCB footprint. Ensure the operating temperature range covers the intended environmental conditions for the application design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high bandwidth and fast settling times are required alongside low power dissipation. The rail-to-rail I/O characteristics make it suitable for single-supply applications where maximizing dynamic range is critical. Consider the 15 mA output drive capability for driving moderate loads without external buffering stages.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8031/AD8032 family of single-supply voltage feedback amplifiers. The AD8031 represents the single-channel version, while the AD8032 provides dual channels in compatible packages. These devices utilize Analog Devices' XFCB process to achieve high speed and low noise performance.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8031ARZ serves as a surface-mount alternative in the SOIC-8 package. Verify pinout compatibility and thermal dissipation requirements when substituting between through-hole and surface-mount variants.
