The LT6202/LT6203/LT6204 are single/dual/quad low noise, rail-to-rail input and output unity gain stable op amps that feature 1.9nV/√Hz noise voltage and draw only 2.5mA of supply current per amplifier. These amplifiers 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.
These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than – 80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems.
The LT6202IS5 is available in the 5-pin TSOT-23 and the 8-pin SO, while the LT6203 comes in 8-pin SO and MSOP packages with standard op amp pinouts. For compact layouts the LT6203 is also available in a tiny fine line leadless package (DFN), while the quad LT6204 is available in the 16-pin SSOP and 14-pin SO packages. These devices can be used as plug-in replacements for many op amps to improve input/output range and noise performance.
