Overview
The TLC2201CDRG4 is a precision, low-noise operational amplifier produced by Texas Instruments. It is part of the TLC220x series, which utilizes the Advanced LinCMOS process. This technology combines the noise performance of low-noise JFET amplifiers with the DC precision of bipolar amplifiers, making it ideal for high-impedance, low-level signal-conditioning applications in both single-supply and split-supply configurations.
The device is known for its excellent DC and noise performance, including low input offset voltage, excellent offset voltage stability with temperature, and a common-mode input voltage range that includes the negative rail. Additionally, it features rail-to-rail output swing, low input bias current, and internal ESD-protection circuits.
