MAX9718

低成本、單聲道/立體聲、1.4W差分音頻功率放大器; ? 2.7V至5.5V單電源工作\n? 217Hz下具有極高的-93dB PSRR\n? 向4Ω負(fù)載提供1.4W輸出功率(每路通道)，具有1%的THD+N \n? 差分輸入\n? 內(nèi)部固定增益以便減少元件數(shù)量\n? 可調(diào)的增益選擇(MAX9718A/MAX9719A) \n? 100nA低功耗關(guān)斷模式\n? 上電/斷電時(shí)，無咔嗒/噼噗聲\n? 改進(jìn)性能、引腳兼容升級(jí)LM4895 (MAX9718D/G)\n? 1.8V邏輯兼容;

MAX9718/MAX9719為差分輸入音頻功率放大器，特別適合用于具有內(nèi)置揚(yáng)聲器的便攜式音頻設(shè)備。差分輸入結(jié)構(gòu)改進(jìn)了噪聲抑制和提供共模抑制。橋接負(fù)載(BTL)結(jié)構(gòu)盡可能地減少了外部元件數(shù)量，同時(shí)提供高質(zhì)量的功率音頻放大。MAX9718為單聲道放大器，而MAX9719為用于立體聲系統(tǒng)的雙聲道放大器。兩種器件均能夠在+5V單電源下向4Ω負(fù)載輸出1.4W連續(xù)的平均功率，且THD+N低于1%。該類器件提供可調(diào)增益的放大器，或0dB、3dB或6dB內(nèi)部固定增益的放大器，以減少元件數(shù)目。\n\n 關(guān)斷輸入模式禁止偏置產(chǎn)生電路和放大器，將靜態(tài)電流損耗減少到100nA以下。MAX9718關(guān)斷輸入能夠設(shè)置為高電平有效或低電平有效。該類器件具有Maxim廣泛應(yīng)用的咔嗒/噼噗聲抑制電路，能夠降低啟動(dòng)和關(guān)斷期間的咔嗒/噼噗聲。\n\n MAX9718引腳兼容于LM4895，采用9焊球UCSP?、10引腳TDFN或10引腳μMAX?封裝。MAX9719采用16引腳TQFN、16引腳TSSOP或16焊球UCSP封裝。兩種器件均工作在-40°C至+85°C的擴(kuò)展級(jí)溫度范圍內(nèi)。\n\n \n\n
