AD7622:  16位、1.5 LSB INL、2 MSPS PulSAR® ADC

AD7622是一款16位、2 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、一个内部基准电压源(和缓冲)、纠错电路,以及串行和并行系统接口端口。它具有两种极高采样速率模式(宽带warp模式和warp模式)和一种快速模式(正常模式),后者适用于异步速率应用。AD7622经过出厂硬件校准和测试,可确保除一般直流参数(增益、偏置和线性度)之外,诸如信噪比(SNR)等交流参数也合乎要求。AD7622只提供无铅封装,工作温度范围为−40°C至+85°C。

The AD7622 is a 16-bit, 2 MSPS, charge redistribution SAR, fully differential, analog-to-digital converter (ADC) 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 (and buffer), error correction circuits, and both serial and parallel system interface ports. It features two very high sampling rate modes (wideband warp and warp) and a fast mode (normal) for asynchronous rate applications. The AD7622 is hardware factory calibrated and tested to ensure ac parameters, such as signal-to-noise ratio (SNR), in addition to the more traditional dc parameters of gain, offset, and linearity. The AD7622 is available in Pb-free only packages with operation specified from −40°C to +85°C.
