一,产品概述(General Description)
The jtm4808 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ω load with 0.1% (THD+N) from a 5V power supply.
audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since
the jtm4808 does not require bootstrap capacitors or snub-ber networks, it is optimally suited for low-power portable systems.The unity-gain stable gain-setting resistors.808 can be configured by external
