Overview
The OPA2335AIDGKRG4 is a dual, single-supply CMOS operational amplifier from Texas Instruments, part of the OPA334 and OPA335 series. These amplifiers utilize auto-zeroing techniques to provide very low offset voltage and near-zero drift over time and temperature. This makes them highly suitable for applications requiring high precision and stability.
