500 MHz四象限乘法器; ? 工作頻率：DC至>500 MHz \n\n? 差分±1 V滿量程輸入 \n\n? 差分±4 mA滿量程輸出電流 \n\n\n\n? 低失真：≦0.05%（0 dBm輸入） \n\n? 電源電壓：±4 V至±9 V \n\n? 低功率（280 mW典型值，VS = ±5 V）;

D834是一款單片、激光調整、四象限模擬乘法器，來自每個差分電壓輸入的跨導帶寬(RL=50 Ω) 超過500 MHz，適合高頻率的應用。在乘法模式下，該器件的典型總滿量程誤差為0.5%，與應用模式和外部電路無關。它的性能相對溫度不敏感，并且由于采用基于帶隙基準電壓發(fā)生器和其他設計功能的穩(wěn)定偏置，其電源會變化。\n\n 為保留高速雙極性工藝的全帶寬潛力以便制造AD834，該器件的輸出采用集電極開路的差分電流對形式。為提供單端地參考電壓輸出，就需要某種形式的外部電流至電壓的轉換。這可以是一個寬帶變壓器、巴倫或有源電路，如運算放大器。在某些應用中（如功率測量），隨之而來的信號處理可能并不需要高帶寬。\n\n 傳遞函數經過精確調整，當X = Y = ±1 V，差分輸出為±4 mA。這種校準可讓兩個或更多AD834器件的輸出以完全相等的權數相加，從而不受負載電路精度的影響。 \n\n AD834J采用8引腳PDIP和塑料SOIC封裝，額定溫度范圍為0°C至70°C商用溫度范圍；AD834A同樣采用8引腳CERDIP封裝和塑料SOIC封裝，工作溫度范圍為?40°C至+85°C工業(yè)溫度范圍。AD834SQ/883B采用8引腳CERDIP封裝，工作溫度范圍為?55°C至+125°C軍用溫度范圍；同時提供S級芯片。\n\n 有關AD834（AN-212 and AN-216）的兩篇應用筆記，可訪問：www.analog.com。欲進一步了解應用電路，請參考AD811數據手冊。\n\n
