AD7243

CMOS、12位串行DACPORT; ? 12位CMOS DAC，內(nèi)置：\n片內(nèi)基準(zhǔn)電壓源\n輸出放大器\n\n? 三種可選輸出范圍：\n-5 V至+ 5 V、0 V至+5 V、0 V至+10 V\n\n? 串行接口;

AD7243是一款完整的12位電壓輸出數(shù)模轉(zhuǎn)換器，單個CMOS芯片上集成輸出放大器和齊納基準(zhǔn)電壓源。無需外部調(diào)整便可實現(xiàn)全部額定性能。\n\n輸出放大器能夠在一個2 kΩ負(fù)載上產(chǎn)生+10V電壓。采用單電源供電時，輸出電壓范圍為0 V至+5 V或0 V至+10 V；采用雙電源供電時，還額外提供±5 V雙極性輸出范圍。輸出范圍通過內(nèi)部增益電阻選擇。\n\n對于兩種單極性范圍，數(shù)據(jù)格式為自然二進(jìn)制，而對于雙極性范圍，可以選擇偏移二進(jìn)制或二進(jìn)制補(bǔ)碼格式。該器件具有CLR清零功能，對于兩種單極性范圍和二進(jìn)制補(bǔ)碼雙極性范圍，可以將輸出設(shè)置為0 V，而對于偏移二進(jìn)制數(shù)據(jù)格式，可以將輸出設(shè)置為-REFIN。此功能可以用作上電復(fù)位，因為它可以將輸出設(shè)置為已知的電平。\n\nAD7243具有一個快速、多功能串行接口，可以輕松連接到配有串行端口的微型計算機(jī)和16位數(shù)字信號處理器。串行數(shù)據(jù)速率最高可達(dá)5 MHz，DAC更新速率可達(dá)300 kHz。同時提供串行數(shù)據(jù)輸出功能，支持多DAC系統(tǒng)以菊花鏈方式連接。這一特性允許系統(tǒng)通過一個簡單的4線接口使用任意數(shù)量的DAC。利用LDAC可以同步更新DAC。\n\nAD7243采用先進(jìn)的線性兼容CMOS (LC2MOS)混合技術(shù)工藝制造，提供16引腳DIP和16引腳SOIC兩種封裝。\n\n\n\nDACPORT是ADI公司的注冊商標(biāo)?\n\n應(yīng)用? 過程控制\n\n? 工業(yè)自動化\n\n? 數(shù)字信號處理系統(tǒng)\n\n? 輸入/輸出端口\n\n\n\n
