5V operation Improved circuitry eliminates pop-click noise during turn-on and turn-off transitions No output coupling capacitors, snubber networks or bootstrap capacitors required Unity-gain stable External gain configuration capability Packages: SOP8 General Description The 8002 is a Class-AB audio power amplifier.
It is capable of delivering 2.
0 watts of continuous average power to an 4Ω BTL load with less than 10% distortion (THD+N) from a 5VDC power supply, or 1.
5 watts continuous average power to an 8 Ω BTL load with less than 1% distortion.
The 8002 is designed specifically to provide high quality output power with a minimal amount of external components.
It does not require output coupling capacitors or bootstrap capacitors.
The 8002 is ideally suited for audio speakers and other low voltage applications.
With special pop-click eliminating circuit, the 8002 provides perfect pop-click characteristic during turn-on and turn-off transitions.
The 8002 is unity-gain stable and can be configured by external gain-setting resistors.
