1122 Discrete Op-Amp

The 1122 is a high performance direct coupled operational amplifier designed specifically for professional audio amplifier applications, which include:

  • Microphone preamplifier where source impedance is between 7k ohm- 20k ohm for noise index below 1 dB
  • Line output amplifier for driving up to loads of 75 ohm
  • Active filters (equalizer circuits)
  • Summing amplifier

FAQ

Do you sell 1122 Opamps for DIY projects or personal use?

Unfortunately, we do not sell the 1122 opamp for DIY projects as we are no longer selling the 1122 opamp for any use other than for older API modules.
