AD7678ACP:18位、100 kSPS PulSAR® ADC

AD7678是一款18位、100 kSPS、电荷再分配SAR型、全差分模数转换器(ADC),采用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、一个内部基准电压缓冲、纠错电路,以及串行和并行系统接口。

AD7678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。

该器件使用ADI公司的0.6微米高性能CMOS工艺制造,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 AD7678 is a 18-bit, 100 kSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 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.

The AD7678 is hardware factory calibrated and is comprehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity.

It is fabricated using Analog Devices’ high-performance, 0.6 micron CMOS process and is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from –40°C to +85°C.
