TYPICAL APPLICATION
DESCRIPTION
Single/Dual/Quad 100MHz,
Rail-to-Rail Input and Output,
Ultralow 1.9nV/
√Hz Noise, Low Power Op Amps
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
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
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.
