AD7621是一款16位、3 MSPS、电荷再分配SAR型、全差分模数转换器(ADC),采用2.5 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、一个内部基准电压缓冲、纠错电路,以及串行和并行系统接口端口。
该器件具有三种采样模式:极高采样速率模式(宽带Warp模式),适用于欠采样应用;快速模式(正常模式),适用于异步转换速率应用;低功耗模式(脉冲模式),适用于低功耗应用,功耗与吞吐量呈比例关系。该器件采用48引脚LQFP或48引脚LFCSP封装,工作温度范围为-40°C至+85°C。
The AD7621 is a 16-bit, 3 MSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 2.5 V power supply. The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports.
It features a very high sampling rate mode (Wideband Warp) for undersampling applications and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput.It is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from –40°C to +85°C
