• Gain Bandwidth Product: 25 MHz
• -3dB Bandwidth: 1 MHz
• Current - Input Bias: 15 nA
• Voltage - Input Offset: 25 µV
• Current - Supply: 3.5 mA
• Voltage - Supply Span: 12V to 36V
• Operating Temperature Range: -25°C to 85°C

Mechanical Compatibility Parameters:

• Amplifier Type: Instrumentation
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: 16-CDIP (0.300", 7.62mm)
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all listed parameters without exception. Deviations in any electrical specification or mechanical characteristic disqualify a part from substitution eligibility.
