Substitute Part Grouping Explanation

Substitution of the AD8066AR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier type, circuit count, output configuration, frequency response, slew rate, bias current, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and physical package dimensions.

The AD8066ARZ qualifies as a direct substitute based on complete parameter alignment across all specified electrical characteristics and mechanical requirements. Both parts share the same base product number (AD8066), identical package configuration (8-SOIC), and equivalent performance specifications.

Key Parameters Determining Substitution:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Slew Rate: 180 V/µs
• -3dB Bandwidth: 155 MHz
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Supply Voltage Range: 5 V to 24 V
• Operating Temperature: -40°C to 85°C

Parameter Comparison

Engineering Selection Recommendations

The AD8066ARZ is the direct substitute for the AD8066AR. Both components are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications across all parameters. The primary distinction is product status: the AD8066AR is obsolete while the AD8066ARZ maintains active status.

Selection of the AD8066ARZ is supported by its ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and ongoing production. The AD8066ARZ is available in tube packaging, whereas the AD8066AR packaging specification was not provided. Both components maintain the same 8-SOIC package footprint and are suitable for direct PCB substitution without layout modifications.
