Description

The TS522 is a monolithic dual operational amplifier mainly dedicated to audio applications. The TS522 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.

1.Either or both input voltages must not exceed the magnitude of VCC+ or VCC-

2.Power dissipation must be considered to ensure maximum junction temperature (Tj) is not exceeded.

3.Short-circuits can cause excessive heating and destructive dissipation.

4.Rth are typical values.

5.Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.

6.Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.

7.Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.
