16位1MSPS模数转换器1LSB INL微分AD7677数据表

　　The AD7677 is a 16-bit， 1 MSPS， charge redistribution SAR， fully differential， 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， error correction circuits， and both serial and parallel system interface ports. The AD7677 is hardware factory calibrated and 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 features a very high sampling rate mode （Warp）; a fast mode （Normal） for asynchronous conversion rate applications; and， for low power applications， a reduced power mode （Impulse） where the power is scaled with the throughput. The AD7677 is available in a 48-lead LQFP or a tiny 48-lead LFCSP with operation specified from –40°C to +85°C.
