LT6203CS8#PBF

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 LT6202 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.
