Frequently Asked Questions
What is the operating temperature range for these op amps?
The continuous operating temperature range is specified as –40°C to 85°C.
How do I connect the power supply when using the LT1368/LT1369?
These devices use compensation requiring a 0.1μF output capacitor, which enhances the amplifier's supply rejection and reduces output impedance.
What are the available package types for different models?
The LT1366/LT1368 come in 8-pin PDIP or 8-lead SO packages, while the LT1367/LT1369 use a standard quad pinout in a 14-lead SO package.
