The OPA2227 uses a bipolar input stage optimized for ultra-low voltage noise (3nV\/sqrtHz) while maintaining low current noise (0.35pA\/sqrtHz). The input stage uses a low-noise differential pair with active load. Precision laser-trimmed thin-film resistors set the input offset voltage to +\/-75uV max. The output stage provides rail-to-rail within 2V of the supplies, driving 600-ohm loads. The 8MHz GBW and 2.3V\/us slew rate support audio-band active filters and precision integrators. The dual configuration halves board space vs two singles.<\/p>\n
