AD7466/AD7467/AD7468*分别是12/10/8位高速、低功耗逐次逼近型模数转换器(ADC),工作电压为1.6V至3.6V单电源,具有低功耗特性,最高呑吐量可达200 kSPS。该器件内置一个低噪声、宽带宽采样保持放大器,可处理3 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。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 AD7466/AD7467/AD7468* are 12-/10-/8-bit, high speed, low power, successive approximation analog-to-digital converters (ADCs), respectively. The parts operate from a single 1.6 V to 3.6 V power supply and feature throughput rates up to 200 kSPS with low power dissipation. The parts contain a low noise, wide bandwidth track-and-hold amplifier, which can handle input frequencies in excess of 3 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 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 V to VDD. The conversion rate is determined by the SCLK.
