G1421F Thông tin chi tiết sản phẩm

General Description
G1421 is a stereo audio power amplifier in 24pin TSSOP thermal pad package. It can drive 1.8W continuous RMS power into 4Ω load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. To simplify the audio system design in the notebook application, G1421 supports the Bridge-Tied Load (BTL) mode for driving the speakers, Single-End (SE) mode for driving the headphone. In the HP-IN mode, it can support a DC value to the phone-jacket and drive the headphone without the audio amplifier outputs coupling capacitors. G1421 can mute the output when Mute-In is activated. For the low current consumption applications, the SHDN mode is supported to disable G1421 when it is idle. The current consumption can be further reduced to below 5µA.
