The OPx13 family of single-supply operational amplifiers features both low noise and drift. It has been designed for systems with internal calibration. Often these processor-based systems are capable of calibrating corrections for offset and gain, but they cannot correct for temperature drifts and noise. Optimized for these parameters, the OPx13 family can be used to take advantage of superior analog performance combined with digital correction.
The OPx13 family of single‑supply operational amplifiers offers ultra‑low noise (4.7 nV/√Hz) and very low drift (0.2 µV/°C) while supporting both single‑ and dual‑supply operation. They are intended for precision systems such as digital scales, strain‑gage instrumentation, battery‑powered devices, and temperature‑transducer amplifiers.
