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, par- ticular 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. s Two and Three Op Amp Instrumentation Amplifiers s Low Noise Signal Processing s Active Filters s Microvolt Accuracy Threshold Detection s Strain Gauge Amplifiers s Direct Coupled Audio Gain Stages s Tape Head Preamplifiers s Infrared Detectors FEATURES DESCRIPTIO APPLICATIO S Protected by U.S. patents 4,775,884 and 4,837,496. , LTC and LT are registered trademarks of Linear Technology Corporation.
