description
The TLC220x, TLC220xA, TLC220xB, and TLC220xY are precision, low-noise operational
amplifiers using Texas Instruments Advanced Lin
CMOS 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 Lin
CMOS 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.
