APX4558
DUAL CHANNEL LOW NOISE GENERAL PURPOSE
OPERATIONAL AMPLIFIER
Description
The APX4558 device is a dual low noise operational
amplifier. The wide bandwidth and low noise make it very
suited to audio applications.
The device is short-circuit protected, and the internal
frequency compensation ensures stability without external
components.

Notes:
2. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
3. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC–.
4. Differential voltages are at IN+ with respect to IN–.
5. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
6. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
7. Maximum power dissipation is a function of TJ (max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature
is PD = (TJ (max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
