LT1124 | Op Amp Upgrade

LT1124
LINEAR TECHNOLOGY
Dual/Quad Low Noise, High Speed Precision Op Amps

The LT®1124 dual and 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 LT1124/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. Consequently, the specifications of even the lowest cost grades (the LT1124C and the LT1125C) have been spectacularly improved compared to equivalent grades of competing amplifiers.
