The LT1125 quad are high performance op amps that offer higher gain, slew rate and bandwidth than the industry standard OP-27 and competing OP‑270/ OP-470 op amps. In addition, the LT1125 have lower I_B and I_OS than the OP-27; lower V_OS and noise than the OP-270/OP-470.

In the design, processing and testing of the device, particular attention has been paid to the optimization of the entire distribution of several key parameters. Slew rate, gain bandwidth and 1kHz noise are 100% tested for each individual amplifier. Consequently, the specifications of even the lowest cost grades (the LT1125C) have been spectacularly improved compared to equivalent grades of competing amplifiers.
