AD608AR Equivalent & Substitute Parts

Part Overview

The AD608AR is an RF mixer integrated circuit designed for down-conversion applications in FM, GSM, PM, and PHS systems operating at 500MHz. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The AD608AR provides 24dB gain with a 16dB noise figure in a 16-SOIC surface mount package, delivering the electrical performance required for intermediate frequency conversion in wireless communication receivers.

Substitute Part Grouping Explanation

Substitution of the AD608AR is determined by strict equivalence across the following critical parameters:

• RF Type and Application: FM, GSM, PM, PHS, FM down-conversion capability
• Operating Frequency: 500MHz center frequency
• Electrical Performance: 24dB gain and 16dB noise figure
• Supply Specifications: 2.7V to 5.5V operating range and 7.3mA supply current
• Package Configuration: 16-SOIC surface mount package with 0.154" (3.90mm) width
• Mixer Count: Single mixer architecture

The AD608ARZ qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional performance across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The AD608ARZ is the direct equivalent substitute for the obsolete AD608AR. Both components share identical electrical performance specifications, package geometry, and functional characteristics across all critical parameters. The AD608ARZ maintains active product status with Analog Devices Inc., ensuring ongoing availability and support.

The AD608ARZ provides additional compliance advantages: ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to environmental and regulatory requirements. The transition from AD608AR to AD608ARZ requires no circuit modifications, as pin configuration, electrical performance, and supply requirements remain unchanged.

Frequently Asked Questions (FAQ)
