日本国家半导体公司(ＮＳ)发表了使用5Ｖ单电源,25ｍＷ功耗的低功率8位Ａ/Ｄ转换器“ＡＤＣ1175—50”。该产品一方面实现了50ＭＨｚ工作目标,同时也适于1Ｍ～55ＭＨｚ的时钟频率。由于它具备极低功耗的ＤＣ·ＡＣ特性,因此它最适用于数字相机、机顶合、凸轮编码器等通信设备方 National Semiconductor Corp. (NS) has released the ADC1175-50, a low-power 8-bit A / D converter that uses a single 5-V supply and 25mW of power. The product on the one hand to achieve the goal of 50MHz, but also suitable for 1M ~ 55MHz clock frequency. Because of its extremely low power consumption DC · AC characteristics, so it is most suitable for digital cameras, set top, cam encoder and other communications equipment side
