The LT1122 JFET input operational amplifier combines  
high speed and precision performance.  
A unique poly-gate JFET process minimizes gate series  
resistance and gate-to-drain capacitance, facilitating wide  
bandwidth performance, without degrading JFET transis-  
tor matching.

It slews at 80V/µs and settles in 340ns. The LT1122 is  
internally compensated to be unity gain stable, yet it has a  
bandwidth of 14MHz at a supply current of only 7mA. Its  
speed makes the LT1122 an ideal choice for fast settling  
12-bit data conversion and acquisition systems.

The LT1122 offset voltage of 120µV, and voltage gain of  
500,000 also support the 12-bit accurate applications.

The input bias current of 10pA and offset current of 4pA  
combined with its speed allow the LT1122 to be used in  
such applications as high speed sample and hold amplifi-  
ers, peak detectors, and integrators.
