Low Distortion Rail-to-Rail Output Op Amps  
FEATURES  
DESCRIPTION  
The LTC®6226/LTC6227 are very fast, low noise rail-to-rail  
output, unity gain stable single/dual op amps, with a gain-  
bandwidth product of 420MHz and a slew rate of 180V/μs.  
The low input referred voltage noise of only 1nV/√Hz and

Supply Current: 5.5mA/Channel Typ  
Operating Supply Range: 2.8V to 11.75V  
Input Offset Voltage: 95μV Max  
Offset Drift :0.4μV/°C  
Low Power Shutdown  
Very High Open Loop Gain: 9V/μV (139dB), R = 1kΩ  
Operating Temp Range: –40°C to 125°C  
Single in 8-Lead SOIC, TSOT-23, 2mm × 2mm DFN.  
Duals in 3mm × 3mm DFN, MS8E  
The combination of low offset, low offset drift, high gain  
(139dB) and high CMRR (114dB) make these excellent  
devices for high dynamic range applications.  
The LTC6226 family maintains excellent performance for  
supply voltages of 2.8V to 11.75V and the devices are fully  
specified at supplies of 3V, 5V and 10V ( 5V).  
L
With an input range extending to the negative rail and  
rail-to-rail output stage, the operational amplifier can  
accommodate wide swinging signals, and true single  
supply operation.  
APPLICATIONS  
n
Optical Electronics: Fast AC-Coupled Transimpedance  
For space constrained applications, the amplifiers come  
in 2mm × 2mm DFN (single) and 3mm × 3mm DFN  
(dual) packages. The devices are also available in 8-lead  
SOIC,TSOT-23 and MS8E.
