STMicroelectronics TS522
Very low noise suitable for audio applications (4.5nV/sqrtHz)
The TS522 device is a monolithic dual operational amplifier mainly dedicated to audio applications. The TS522 device offers a very low input offset voltage as well as low voltage noise (4.5 nV/√ Hz) and high dynamic performances (15 MHz gain bandwidth product, 7 V/μs slew rate). The output stage allows a large output voltage swing and symmetrical source and sink currents.
