Overview
The OPA2727AIDRBR is a high-precision, dual-channel operational amplifier produced by Texas Instruments. It is part of the OPAx727 and OPAx728 family, which utilizes a state-of-the-art 12V analog CMOS process. This op amp is known for its excellent DC and AC performance, making it suitable for a variety of high-end applications. The device features an extremely low input offset voltage and drift, achieved through Texas Instruments' e-trim technology, which involves digital trimming after packaging to compensate for parameter shifts during the manufacturing process.
