The LT6203CS8#PBF is a dual low noise rail-to-rail input and output unity gain stable Operational Amplifier that feature 1.9nV/√Hz noise voltage and draw only 2.5mA of supply current per amplifier. The amplifier combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/μs slew rate and are optimized for low supply signal conditioning systems. The amplifier maintain their performance for supplies from 2.5 to 12.6V and are specified at 3, 5 and ±5V supplies. Harmonic distortion is less than -80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems. The devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance.
