(Plastic Micropackage)
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 V
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.

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.
