PAM8124RHR

A Product Line of Diodes Incorporated PAM8124 HIGH POWER AUDIO Description Pin Assignments TSSOP-24-EP driving stereo speakers in a single-ended configuration; or a mono PVCCL 1 SDN 2 PVCCL 3 MUTE 4 LIN 5 RIN 6 VCM 7 AGND 8 AGND 9 PVCCR 10 VCLAMP 11 PVCCR 12 speaker in a bridge-tied-load configuration. The PAM8124 can drive stereo speakers (SE) as low as 4Ω. Due to the low power dissipation and high efficiency, up to 95%, the device can be used without any external heat sink when playing music. The gain of the amplifier is controlled by 2 gain selectable pins, offering 20dB, 26dB, 32dB, and 36dB gain selections. The PAM8124 is available in a TSSOP-24-EP package.
