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.
