TS522

Precision low noise dual operational amplifier

Datasheet − production data

Features

■ Large output voltage swing: +14.3 V/-14.6 V

■ Low input offset voltage 850 μV max.

■ Low voltage noise: 4.5 nV/√Hz

■ High gain bandwidth product: 15 MHz

■ High slew rate: 7 V/μs

Description

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.
