Frequently Asked Questions
What is the typical operational temperature range for these op amps?
The operating temperature range is from –40°C to 85°C.
Can the programmable current option save power while maintaining performance?
Yes, using the programmable current option (LT1815 and LT1816A) allows for power savings by operating at reduced supply current, while keeping comparable supply current specifications.
What is the maximum input slew rate of these amplifiers?
These are high-speed operational amplifiers with a maximum slewing rate measured in 1500V/µs.
Does the output performance vary when running on single vs. dual supplies?
When specified at ±5V, the output to a 100Ω load is ±3.8V, but on a single 5V supply, it swings from 1V to 4V.
