3 V to 5 V Single Supply, 200 kSPS 12-Bit Sampling ADCs

GENERAL DESCRIPTION The AD7854/AD7854L is a high speed, low power, 12-bit ADC that operates from a single 3 V or 5 V power supply, the AD7854 being optimized for speed and the AD7854L for low power. The ADC powers up with a set of default conditions at which time it can be operated as a read-only

3 V至5 V单电源、200 kSPS、12位并行采样ADC

AD7854/AD7854L均为高速、低功耗、12位ADC，采用3 V或5 V单电源供电，二者分别针对速度和低功耗进行了优化。当满足一组默认条件时，ADC上电，此时可作为只读ADC使用。两款ADC都含有自校准和系统校准选项，可确保操作精度不受时间和温度影响，还具有适合低功耗应用的多个省电选项。\nAD7854的吞吐量可达200 kHz，而AD7854L的吞吐量可达100 kHz。通过输入采样保持功能可在500 ns内采集一个信号，并采用伪差分采样方案。AD7854和AD7854L的输入电压范围为0至VREF（单极性）和以VREF/2为中心的-VREF/2至+VREF/2（双极性）。在单极性方式 额定电压（VDD）：3 V至5.5 V\n只读操作\nAD7854–200 kSPS；AD7854L–100 kSPS\n系统校准和自校准\n灵活的并行接口\n12位并行/8位并行（AD7854）\n28引脚DIP、SOIC和SSOP封装（AD7854）\n低功耗：\n- 正常工作模式\nAD7854：15 mW （VDD = 3 V）\nAD7854L：5.5 mW （VDD = 3 V）\n- 转换后自动关断（25 µW）\nAD7854：1.3 mW （10 kSPS）\nAD7854L：650 µW （10 kSPS）;
