LT1122CS8#PBF

LT®1122 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 transistor matching. Typical applications include 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 and peak detectors.
