About LM359:
The LM359 consists of two electric current differencing (Norton) input amplifiers. Design emphasis has been installed on acquiring high frequency functionality and giving user programmable amplifier operating characteristics. Each amplifier is broadbanded to deliver a high gain bandwidth product, fast slew rate and stable operation for an inverting closed loop gain of 10 or bigger. Pins for extra external frequency compensation are available. The amplifiers are intended to work from a single supply and can accommodate input common-mode voltages higher than the voltage supply.

LM359 Applications:

  • General purpose video amplifiers
  • Photo-diode amplifiers
  • High frequency, high Q active filters
  • Wide frequency range waveform generation circuits
  • All LM3900 AC applications work to much higher frequencies
