Electrical Parameters (Must Match):

• Amplifier Type: Differential
• Number of Circuits: 1
• Output Type: Differential, Rail-to-Rail
• Slew Rate: 450 V/µs
• -3dB Bandwidth: 110 MHz
• Current - Input Bias: 500 nA
• Voltage - Input Offset: 700 µV
• Current - Supply: 3.2 mA
• Current - Output / Channel: 20 mA
• Voltage - Supply Span: 2.7 V to 12 V
• Operating Temperature Range: -40°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

The AD8137YRZ qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence. The primary distinction is product status and packaging format.
