Instructions for CA3085

1. Supply Voltage Setup:

   • Ensure the supply voltage is within the specified range of -18V to +30V.

2. Input Connections:

   • Connect input signals ensuring that the input bias and offset currents are within the specified limits (-1nA to +1nA and -0.7mV to +0.7mV respectively).

3. Output Configuration:

   • Be cautious with output connections as the device can withstand short circuits for more than 60 seconds, but prolonged exposure may affect performance.

4. Operational Amplifier Usage:

   • For optimal performance, operate within the bandwidth limit (typically 1.5 MHz) and consider the slew rate of 0.3 V/μs when designing signal processing paths.

5. Temperature Considerations:

   • The parameters provided are typically measured at 25°C. Performance can vary outside this temperature, so ensure proper thermal management in your design.

6. Handling Static Electricity:

   • The CA3085 is sensitive to static electricity; use appropriate handling procedures to prevent damage.

7. Circuit Protection:

   • Incorporate necessary protection circuits such as clamping diodes or resistors to protect against overvoltage conditions.

This table and set of instructions provide a comprehensive overview of the CA3085's key parameters and usage guidelines.
