Substitute Part Grouping Explanation

Substitution eligibility for the MAX4222EEE is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier type: Buffer, Voltage Feedback
• Number of circuits: 4 independent channels
• Output configuration: Rail-to-Rail
• Slew rate: 600V/µs
• Bandwidth (-3dB): 200 MHz
• Input bias current: 5.4 µA
• Input offset voltage: 4 mV
• Supply current: 5.5 mA
• Output current per channel: 120 mA
• Supply voltage range: 3.15V to 11V
• Temperature range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Package type: 16-SSOP
• Mounting: Surface Mount
• Physical dimensions: 0.154" width, 3.90mm width

Substitute parts must match all electrical parameters and maintain mechanical compatibility with the original 16-QSOP package specification. Packaging format (tube vs. alternative) does not affect electrical or mechanical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations
