具有IVSENSE、超低IQ和掉電保護(hù)功能的28V數(shù)字輸入DG類放大器

MAX98397是一款高效率、單聲道DG類揚(yáng)聲器放大器，具有業(yè)界出色的靜態(tài)功耗，集成了揚(yáng)聲器電流和電壓檢測(cè)(IVSENSE)、掉電保護(hù)引擎(BPE)和動(dòng)態(tài)裕量跟蹤(DHT)功能。該器件支持高達(dá)192kHz的采樣速率、更高的通帶（對(duì)于fS > 50kHz），并為通過放大器的超聲信號(hào)提供旁路路徑，使其不會(huì)因音頻處理而衰減，因此還有助于實(shí)現(xiàn)超聲應(yīng)用。通過高精度的輸出電流監(jiān)控(ISENSE)和電壓監(jiān)控(VSENSE)，主機(jī)設(shè)備能夠運(yùn)行揚(yáng)聲器保護(hù)算法。擴(kuò)頻調(diào)制(SSM)和邊緣速率控制可充分降低EMI，并且無需像傳統(tǒng)D類器件中一樣進(jìn)行輸出濾波。\n\n 為了實(shí)現(xiàn)業(yè)界出色的靜態(tài)功耗，DG類架構(gòu)采用 ? 寬輸入電源范圍（3V至28V）\n? DG類操作可實(shí)現(xiàn)業(yè)界出色的靜態(tài)功耗\n? 25.3mW（VPVDD = 24V、VVBAT = 5.0V時(shí)）\n? 超低噪底\n? 117.8dB動(dòng)態(tài)范圍\n? 低失真\n? -85dB THD+N（為4Ω負(fù)載提供6W功率時(shí)，f = 1kHz）\n? -80dB THD+N（為8Ω負(fù)載提供1W功率時(shí)，f = 6kHz，F(xiàn)SW = 650kHz） \n? 輸出功率：\n? 為4Ω負(fù)載提供26W，VPVDD = 16V，THD+N = 1%\n? 為8Ω負(fù)載提供51W，VPVDD = 28V，THD+N = 10%\n? 為4Ω負(fù)載提供10;
