The LTC6078 and LTC6079 are dual and quad micropower, precision op amps that combine the low offset and drift of traditional bipolar amplifiers with the low bias current of CMOS amplifiers. Additionally, the LTC6078 features low supply current and low noise, low supply voltage operation, and rail-to-rail input and output stages. This combination of features allows precision performance previously available only through composite amplifiers, manual offset trimming, or calibration.
