Description
Feature:This power amplifier module has the protection function of undervoltage, overcurrent, output short circuit, sho rt circuit test when full power output, in the design reserved the port such as turn off control, silent control, an d has the output fault report output, more convenient secondary development in the application!
Product parameters:
Supply voltage: DC-12V-22VChip voltage range: DC8V-26VRated power: 20W+20WOutput impedance: 4-8 ohmsPeak power: 35W+35WDynamic current: 4AStatic current: 40 maTurn off current: 1uAGain: 35 dbOutput impedance: about 20K ohm PCB size: 38mm*20mm*2.8mm thickPin: 2.54*12*4mm
Pin definition:
LIN: Left channel signal inputAGND: Signal groundRIN: Right channel signal inputGND: Power groundVCC: Power positiveFAULT: Fault indicatorMUTE: Mute controlSD: Off controlRO-: Right channel output negativeRO + : Positive right channel outputLO+: positive left channel outputLO-: Left channel output negative
Note: In simple applications, the three red pins do not require wiring.The fault indication is the indication of hi gh level when output short circuit, the mute high level is effective, and the turn off low level is effective.
Package includes:
1 x Digital Amplifier Modul
