AD8066ARM Equivalent & Substitute Parts

Part Overview

The AD8066ARM is a voltage feedback amplifier manufactured by Analog Devices Inc., featuring dual circuits in a rail-to-rail configuration. This linear amplifier is housed in an 8-MSOP surface mount package and is classified as obsolete. The AD8066ARM series is part of the FastFET™ product line, designed for applications requiring high-speed signal amplification with controlled slew rates and bandwidth characteristics.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing production support, design updates, and inventory management. Direct manufacturer substitutes with active product status provide continuity for applications currently utilizing the AD8066ARM.

Substitute Part Grouping Explanation

Substitution of the AD8066ARM is determined by electrical and mechanical parameter equivalence. The primary substitute identified is the AD8066ARMZ, which maintains identical electrical specifications across all critical performance parameters: amplifier type, circuit count, output configuration, slew rate, bandwidth, input bias current, input offset voltage, supply current, output current capability, supply voltage range, and operating temperature range.

Both components share the same base product number (AD8066), package designation (8-MSOP), and mounting type (surface mount). The key differentiator between the main part and its substitute is product status and packaging format. The AD8066ARM is classified as obsolete, while the AD8066ARMZ maintains active product status. Additionally, the AD8066ARMZ is supplied in tube packaging, whereas the AD8066ARM packaging format is not specified in the provided data.

Substitution is valid when all of the following parameters match:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Slew Rate: 180 V/µs
• -3dB Bandwidth: 120 MHz
• Current - Input Bias: 3 pA
• Voltage - Input Offset: 400 µV
• Current - Supply: 6.6 mA (x2 Channels)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 5 V to 24 V
• Operating Temperature: -40°C to 85°C
• Package / Case: 8-MSOP

Parameter Comparison

Engineering Selection Recommendations

The AD8066ARMZ is the direct substitute for the AD8066ARM. Both components are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications. All critical performance parameters—including slew rate, bandwidth, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature—are equivalent.

The primary distinction is product status: the AD8066ARM is obsolete, while the AD8066ARMZ maintains active product status. The AD8066ARMZ also carries ROHS3 compliance and REACH unaffected status, providing additional regulatory alignment for applications subject to environmental and hazardous substance restrictions.

For new designs or production continuity, the AD8066ARMZ is the appropriate selection. The component maintains full electrical and mechanical compatibility with the AD8066ARM, ensuring direct substitution without circuit redesign or board layout modifications.
