APX4558 DUAL CHANNEL LOW NOISE GENERAL PURPOSE OPERATIONAL AMPLIFIER Description Pin Assignments (T(Topop View) View) The APX4558 device is a dual low noise operational amplifier. The wide bandwidth and low noise make it very 1OUT1OUT 11 VV 88 CC+CC+ suited to audio applications. 1IN-1IN- 2OUT2OUT 22 77 The device is short-circuit protected, and the internal 1IN+1IN+ 2IN-2IN- 33 frequency compensation ensures stability without external 66 components. VV 2IN+2IN+ 4545 CCCC-- SO-SO-88 Features Applications Audio pre amps Unity-Gain Bandwidth . 3 MHz typical Gain and Phase match between amplifiers RCA line out buffers Low Noise . 8 nV/ Hz typical at 1 kHz Wide Common-Mode and Differential voltage ranges No frequency compensation required Low power consumption No latch-up Green mold compound (No Br, Sb) (Note 1) Notes: 1.

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 and V CC+ CC. 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 (max), , and T . The maximum allowable power dissipation at any allowable ambient temperature J JA A is P = (T (max) T )/ . Operating at the absolute maximum T of 150 C can affect reliability.
