DUAL CHANNEL LOW NOISE GENERAL PURPOSE

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 V

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 T is P
