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.

PPLICATI

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.
