AD7651ACP:16位、100 kSPS、内置基准电压源的PulSAR®单极性ADC
AD7651是一款16位、100 kSPS、电荷再分配SAR型模数转换器（ADC）,采用5 V单电源供电。该器件内置一个16位高速采样ADC、一个内部转换时钟、一个内部基准电压源、纠错电路,以及串行和并行系统接口端口。该器件采用ADI公司的0.6微米高性能CMOS工艺制造,成本很低；提供48引脚LQFP或微型48引脚LFCSP两种封装；工作温度范围为-40°C至+85°C。
The AD7651 is a 16-bit, 100 kSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports.It is fabricated using Analog Devices' high-performance, 0.6 micron CMOS process, with correspondingly low cost and is available in a 48-lead LQFP and a tiny 48-lead LFCSP with operation specified from -40°C to +85°C
