LT1079CN#PBF

LT1079 is a micropower, single supply, precision quad op-amp. This device is optimized for single supply operation at 5V. ±15V specifications are also provided. Micropower performance of competing devices is achieved at the expense of seriously degrading precision, noise, speed and output drive specifications. The design effort of the LT1079 was concentrated on reducing supply current without sacrificing other parameters. The offset voltage achieved is the lowest on any dual nonchopper stabilized op-amp micropower or otherwise. Offset current, voltage and current noise, slew rate and gain bandwidth product are all two to ten times better than on previous micropower op-amps. The 1/f corner of the voltage noise spectrum is at 0.7Hz, at least three times lower than on any monolithic op-amp. Application includes battery or solar-powered systems, portable Instrumentation, remote sensor amplifier, satellite circuitry, micropower sample-and-hold, thermocouple amplifier, micropower filters.
