EVAL-AD7266EDZ

转换过程和数据采集过程均采用标准控制输入，可与微处理器或DSP轻松接口。输入信号在CS的下降沿进行采样，而转换同时在此处启动。转换时间取决于SCLK频率。AD7266 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。其工作电压为5 V，呑吐量达2 MSPS，而最大功耗仅为4 mA。采用正常运行模式时，该器件还具有灵活的功耗/呑吐量管理能力，这要归功于超低的静态电流消耗水平。

Its analog input range is 0 V to V_REF (or 2 × V.)_REF ）之间进行选择，可采用标准二进制或二进制补码输出编码。AD7266 拥有2.5 V的片内参考电压，需用外部参考电压时，可超过此值，外部参考范围为100 mV至V_DD 。AD7266提供32引脚LFCSP和32引脚TQFP两种封装。Product Focus

1. Two complete ADC functions enable simultaneous sampling and conversion of two channels. Each ADC can be programmed to be set to three all/pseudo differential pairs or six single-ended inputs. The conversion results of the two channels can be obtained simultaneously by independent data lines, and if only one serial port is available, the conversion results can be obtained sequentially through one data line.
2. 高呑吐量、低功耗。AD7266拥有2 MSPS的呑吐量，工作电压为3 V时，最大功耗仅有9 mW。
3. AD7266同时提供标准0 V至V_REF Input range and 2 × V_REF Input range.
4. No pipeline delay. The device uses two standard successive approximation ADCs to pass.CSInput and one-time conversion control enables precise control of sampling time.
