高级LinCMOSE低噪声精密运算放大器 Advanced LinCMOSE LOW-NOISE PRECISION OPERATIONAL AMPLIFIERS

description

The TLC220x, TLC220xA, TLC220xB, and TLC220xY are precision, low-noise operational amplifiers using Texas Instruments Advanced LinCMOSprocess. These devices combine the noise performance of the lowest-noise JFET amplifiers with the dc precision available previously only in bipolar amplifiers. The

Advanced LinCMOSprocess uses silicon-gate technology to obtain input offset voltage stability

with temperature and time that far exceeds that obtainable using metal-gate technology. In addition, this technology makes possible input impedance levels that meet or exceed levels offered by top-gate JFET and expensive dielectric-isolated devices.
