美国国家半导体公司推出采用连续时间sigma-delta(CTSD)技术的高速ADC。这款8通道、12位、50MSPS的ADC12EU050属于PowerWise高能效芯片系列产品。该产品的无混叠信号采样带宽高达25MHz,并且功耗比采用流水线架构的同类竞争产品低一半(只有350mW)。这款芯片在低功率技术上取得新
National Semiconductor Introduces High-Speed ADCs Using Continuous-Time sigma-delta (CTSD) Technology. The 8-channel, 12-bit, 50MSPS ADC12EU050 belongs to the PowerWise energy-efficient chip family. The product has aliasing-free signal sampling bandwidths up to 25MHz and consumes less than half the power (350mW) of competing products in a pipeline architecture. This chip made new in low-power technology
