LT1122DS8#PBF

LT®1122 JFET input fast settling 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 transistor matching. This 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 12bit data conversion and acquisition systems. Applications are fast 12bit D/A output amplifiers, high speed buffers, fast sample-and-hold amplifiers, high speed integrators, voltage to frequency converters, active filters, log amplifiers, peak detectors.
