AD7277是一款10位高速、低功耗的逐次逼近型ADC。工作电压为:2.35V至3.6 V单电源,最高呑吐量可达3 MSPS。内部包含一个低噪声、宽带宽采样/保持放大器,可处理30 MHz以上的输入频率。转换过程和数据采集过程通过/CS和串行时钟进行控制,从而为器件与微处理器或DSP接口创造了条件。输入信号在/CS的下降沿进行采样,而转换同时在此处启动。该器件不存在流水线延迟。AD7277采用先进的设计技术,可在高呑吐量的情况下实现极低的功耗。该器件采用内部基准电压,从VDD直接获得,从而为ADC提供了最宽的动态输入范围,因此,其模拟输入范围为0至VDD。转换速率取决于SCLK。
The AD7277 is a 10-bit, high speed, low power, successive-approximation ADC. The part operates from a single 2.35V to 3.6 V power supply and features throughput rates up to 3 MSPS. The part contains a low-noise, wide bandwidth track/hold amplifier which can handle input frequencies in excess of 30 MHz.
The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and the conversion is also initiated at this point. There are no pipeline delays associated with the part.The AD7277 uses advanced design techniques to achieve very low power dissipation at high throughput rates.The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus the analog input range for the part is 0 to VDD. The conversion rate is determined by the SCLK
