The LT1126 dual and LT1127 quad are high performance, decompensated op amps that offer higher slew rate and bandwidth than the LT1124 dual and the LT1125 quad operational amplifiers. The enhanced AC performance is available without degrading DC specs of the LT1124/LT1125. Both LT1126/LT1127 are stable in a gain of 10 or more.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 LT1126C and the LT1127C) have been enhanced.Power consumption of the dual LT1126 is less than one half of two OP-37s. Low power and high performance in an 8-pin SO package makes the LT1126 a first choice for surface mounted systems and where board space is restricted.ApplicationsTwo and Three Op Amp Instrumentation AmplifiersLow Noise Signal ProcessingActive FiltersMicrovolt Accuracy Threshold DetectionStrain Gauge AmplifiersDirect Coupled Audio Gain StagesTape Head PreamplifiersMicrophone PreamplifiersAccelerometer AmplifiersInfrared Detectors
