16位、串行輸入、環(huán)路供電、4MA至20MA DAC

AD5421是一款完整的環(huán)路供電型4 mA-20 mA數(shù)模轉(zhuǎn)換器(DAC)，專為滿足工業(yè)控制領(lǐng)域智能發(fā)射器制造商的需求而設(shè)計(jì)。作為一種完全集成的高精度、低成本解決方案，該器件采用緊湊型TSSOP和LFCSP封裝。\n\n AD5421內(nèi)置一路穩(wěn)壓輸出，用于為自身及發(fā)射器中的其它器件供電。此調(diào)節(jié)器提供1.8 V至12 V的調(diào)節(jié)輸出電壓。該器件還內(nèi)置1.22 V和2.5 V基準(zhǔn)電壓源，因而不需要分立調(diào)節(jié)器和基準(zhǔn)電壓源。\n\n AD5421可以結(jié)合標(biāo)準(zhǔn)HART? FSK協(xié)議通信電路使用，而且額定性能不會(huì)受到影響。高速串行接口能夠以30 MHz速率工作，并且允許通過一個(gè)SPI兼容 ? 16位分辨率和單調(diào)性\n\n? 引腳可選的NAMUR兼容范圍\n? 4 mA至20 mA\n\n? 3.8 mA至21 mA\n\n? 3.2 mA至24 mA\n\n\n\n\n? NAMUR兼容報(bào)警電流\n? 下限報(bào)警電流 = 3.2 mA\n\n? 上限報(bào)警電流 = 22.8 mA/24 mA\n\n\n\n\n? 總非調(diào)整誤差(TUE)：0.05%（最大值）\n\n? 積分非線性(INL)誤差：0.0035% FSR（最大值）\n\n? 輸出溫度系數(shù)：3 ppm/°C（典型值）\n\n? 靜態(tài)電流：300 μA（最大值）;
