FEATURE
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/
μ
s 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 120
μ
V, 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.
