Technical content

2011, January, ver.01 Dual Operational Amplifiers The IL1458 is general purpose dual operational amplifiers. The high common-mode input voltage range and the absence of latch-up make these amplifiers ideal for voltage follower application. The devices are short circuit protected and the internal frequency compensation ensures stability without external components.

  • Short Circuit Protection
  • Wide common-mode and differential ranges
  • No frequency compensation required
  • Low power consumption
  • No latch-up
  • 3 MHz unity gain bandwidth guaranteed
  • Gain and phase match between amplifiers IL1458

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
