低失真 (-120dB)、低噪聲 (4.5nV/rtHz)、雙路音頻運算放大器

OPA1678（雙通道）和 OPA1679（四通道）運算放大器較音頻電路中常用的傳統(tǒng)運算放大器而言，可提供更高的系統(tǒng)級性能。OPA167x 放大器在 1kHz 時可實現(xiàn) 4.5nV/√Hz 的低噪聲密度和 0.0001% 的低失真度，從而提高了音頻信號保真度。它們在 2kΩ 負(fù)載下還提供 800mV 范圍內(nèi)的軌至軌輸出擺幅，從而增加余量并實現(xiàn)動態(tài)范圍最大化。\n\nOPA1678 和 OPA1679 可在 ±2.25V 至 ±18V（或 4.5V 至 36V）的極寬電源電壓范圍內(nèi)工作，電源電流僅為 2mA，因此可適應(yīng)許多類型的音頻產(chǎn)品的電源限制。這些運算放大器是單位增益穩(wěn)定型放大器，且 ? 低噪聲：1kHz 時為 4.5nV/√Hz \n? 高開環(huán)增益：114dB\n? 低靜態(tài)電流： \n? 低輸入偏置電流：10pA（典型值）\n? 寬增益帶寬：16MHz (G = 1)\n? 軌至軌輸出\n? ±2.25V 至 ±18V 或 4.5V 至 36V\n? 雙通道和四通道版本\n? 雙通道：SO-8、MSOP-8、SON-8\n? 四通道：SO-14、TSSOP-14、QFN-16;
