The LT1125CSW#PBF is a quad high performance Operational Amplifier 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 IB and IOS than the OP-27, lower VOS 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.
