(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.

Package information TS522

4 Package information

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com
