The LT1124 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 IBand IOSthan the OP-27; lower VOSand 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.Power consumption of the LT1124 is one-half of two OP-27s. Low power and high performance in an 8-pin SO package make the LT1124 a first choice for surface mounted systems and where board space is restricted.For a decompensated version of these devices, with three times higher slew rate and bandwidth, please see the LT1126/LT1127 data sheet.ApplicationsTwo and Three Op Amp Instrumentation AmplifiersLow Noise Signal ProcessingActive FiltersMicrovolt Accuracy Threshold DetectionStrain Gauge AmplifiersDirect Coupled Audio Gain StagesTape Head PreamplifiersInfrared Detectors
