LT1078ACN8#PBF

LT1078ACN8#PBF is a micropower dual opamp. This device is optimized for single supply operation at 5V. 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 device 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 opamps. The 1/f corner of the voltage noise spectrum is at 0.7Hz, at least three times lower than on any monolithic opamp. It is used in applications such as battery or solar-powered systems, portable instrumentation, remote sensor amplifiers, satellite circuitry, micropower sample-and-hold, thermocouple amplifiers, and micropower filters.
