DESCRIPTION
The LTC
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 amplifi er. These amplifi ers 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 amplifi ers maintain their performance for supplies
from 2.5V to 12.6V and are specifi ed at 3V, 5V and ±5V
supplies. Harmonic distortion is less than – 80dBc at
1MHz making these amplifi ers 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 fi ne 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.
