™

) Package

The LT

®

6202/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 pack-

ages 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.
