Overview
The TLC072CDRG4 is a member of the TLC07x family of wide-bandwidth, high-output-drive single-supply operational amplifiers developed by Texas Instruments. These amplifiers are designed using TI's patented LBC3 BiCMOS process, combining the high input impedance and low noise of a CMOS front end with the high-drive capability of a bipolar output stage. This design provides optimal performance for a variety of applications, including audio, automotive, industrial, and instrumentation.
The TLC072CDRG4 is particularly suited for users transitioning from dual-supply to single-supply systems and requiring higher AC and DC performance. It operates over a wide supply voltage range of 4.5 V to 16 V and is available in various temperature ranges, including commercial (0°C to 70°C) and extended industrial (−40°C to 125°C) options.
