AD8055ARZ-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8055ARZ-REEL is a single-channel, low-cost voltage feedback operational amplifier manufactured by Analog Devices. It features a typical gain-bandwidth product of 300 MHz and a slew rate of 1400 V/µs. The device operates on dual ±5 V or single +12 V supplies with a quiescent current of approximately 6.5 mA per amplifier. It provides an output drive current exceeding 60 mA and maintains excellent video specifications, including 0.01% differential gain error and 0.02° differential phase error into a 150 Ω load.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Low noise density of 6 nV/√Hz for signal integrity
• Capable of driving heavy loads with over 60 mA output current
• Excellent video linearity with minimal differential gain and phase errors

Instrumentation, Op Amps, Buffer Amps Applications

• Video line drivers
• Photodiode preamplifiers
• Differential line drivers
• A-to-D drivers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm package type and reel size. The REEL7 designation indicates a 7-inch tape and reel packaging format. Confirm that the component meets RoHS compliance standards as indicated by the Z suffix in related part numbers. Ensure the extended temperature range rating matches the application requirements before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier when high speed and low cost are required simultaneously. It offers performance typically found in current feedback amplifiers but with easier voltage feedback usability. Consider the 60 mA output capability for driving multiple video loads or low impedance cables. Verify power dissipation limits under heavy load conditions to ensure junction temperatures remain within safe operating areas.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8055/AD8056 family of low-cost, high-speed voltage feedback amplifiers. The AD8055 is the single-channel version, while the AD8056 is the dual-channel variant. Both share similar electrical characteristics and are designed for portable and battery-powered applications where size and power consumption are critical constraints.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8055AN serves as a lead-free PDIP alternative. The AD8055ART-R2 is available in a smaller SOT-23 package. Cross-reference pinouts and thermal characteristics when substituting packages.
