TLC220x, TLC220xA, TLC220xB, TLC220xY are Texas Instruments Advanced LinCMOS process precision, low-noise operational amplifiers. 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. The combination of excellent dc and noise performance with a common-mode input voltage range that includes the negative rail makes these devices an ideal choice for high-impedance, low-level signal-conditioning applications in either single-supply or split-supply operation.
The TLC220x, TLC220xA, TLC220xB, and TLC220xY are precision, low‑noise operational amplifiers built with Texas Instruments' Advanced LinCMOS™ process. They combine the low‑noise performance of JFET amplifiers with the DC precision of bipolar devices, offering excellent input offset stability and rail‑to‑rail operation for high‑impedance, low‑level signal‑conditioning applications.
