LT6202/LT6203/LT6204
Single/Dual/Quad 100MHz,
Rail-to-Rail Input and Output,
Ultralow 1.9nV/Hz Noise, Low Power Op Amps
FEATURES DESCRIPTION
n
Low Noise Voltage: 1.9nV/Hz (100kHz)
The LT 6202/LT6203/LT6204 are single/dual/quad low
n
Low Supply Current: 3mA/Amp Max
noise, rail-to-rail input and output unity gain stable op amps
n
Gain Bandwidth Product: 100MHz
that feature 1.9nV/Hz noise voltage and draw only 2.5mA
n
Dual LT6203 in Tiny DFN Package
of supply current per amplifier. These amplifiers combine
n
Low Distortion: 80dB at 1MHz
very low noise and supply current with a 100MHz gain
n
Low Offset Voltage: 500V Max
bandwidth product, a 25V/s slew rate, and are optimized
n
Wide Supply Range: 2.5V to 12.6V
for low supply signal conditioning systems.
n
Input Common Mode Range Includes Both Rails
These amplifiers maintain their performance for supplies
n
Output Swings Rail-to-Rail
from 2.5V to 12.6V and are specified at 3V, 5V and 5V
n
Common Mode Rejection Ratio 90dB Typ
supplies. Harmonic distortion is less than 80dBc at
n
Unity Gain Stable
1MHz making these amplifiers suitable in low power data
n
Low Noise Current: 1.1pA/Hz
acquisition systems.
n
Output Current: 30mA Min
n
The LT6202 is available in the 5-pin TSOT-23 and the 8-pin
Operating Temperature Range 40C to 125C
n
SO, while the LT6203 comes in 8-pin SO and MSOP pack-
Low Profile (1mm) SOT-23 (ThinSOT ) Package
ages with standard op amp pinouts. For compact layouts
APPLICATIONS
the LT6203 is also available in a tiny fine line leadless
package (DFN), while the quad LT6204 is available in the
n
Low Noise, Low Power Signal Processing
16-pin SSOP and 14-pin SO packages. These devices
n
Active Filters
can be used as plug-in replacements for many op amps
n
Rail-to-Rail Buffer Amplifiers
to improve input/output range and noise performance.
