AD7476/AD7477/AD7478*分别是12位、10位和8位高速、低功耗逐次逼近型ADC,采用单电源工作,电源电压为2.35V至5.25V,最高呑吐量可达1 MSPS。每个器件均内置一个低噪声、宽带宽采样-保持放大器,可处理6 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。这三款器件均无流水线延迟。AD7476/AD7477/AD7478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。基准电压从VDD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 AD7476/AD7477/AD7478* are, respectively, 12-bit, 10-bit, and 8-bit, high speed, low power, successive approximation ADCs. The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. Each part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 6 MHz.The conversion process and data acquisition are controlled using CS 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 initiated at this point. There are no pipeline delays associated with these parts.
The AD7476/AD7477/AD7478 use advanced design techniques to achieve very low power dissipation at high throughput rates. The reference for the parts is taken internally from VDD. This allows the widest dynamic input range to the ADC. Thus, the analog input range for the parts are 0 V to VDD. The conversion rate is determined by the SCLK.
