AD7641:  18-Bit, 2 MSPS SAR ADC

AD7641是一款18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18位高速采样ADC、一个内部转换时钟、一个内部基准电压源缓冲、纠错电路,以及串行和并行系统接口端口。它具有一种极高采样速率模式(Warp模式)和一种快速模式(正常模式),后者适用于异步转换速率应用。AD7641经过出厂硬件校准和全面测试,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)和总谐波失真(THD)等交流参数也合乎要求。工作温度范围为−40°C至+85°C。

The AD7641 is a 18-bit, 2 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 18-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 (Warp) and a fast mode (Normal) for asynchronous conversion rate applications.

The AD7641 is hardware factory calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) in addition to the more traditional dc parameters of gain, offset and linearity.Operation is specified from −40°C to +85°C.
