AD7660:16位无失码、100 kSPS、CMOS逐次逼近型 PulSAR® ADC
AD7660是首款新一代16位ADC,以极低成本提供真正的16位性能。这款新一代器件基于一种真正的突破性架构的Pulsar内核,为业界最快且精度最高的SAR ADC提供动力。AD7660无流水线延迟,非常适合工业过程控制、多路复用数据采集系统、DSP芯片接口、便携式设备和医疗仪器仪表应用。它拥有90 dB 信纳比（SINAD）,10 kHz时的总谐波失真（THD）为96 dB,以及16位直流精度（无失码）。积分非线性（INL）最大值为±3 LSB,微分非线性（DNL）最大值为1.75 LSB。100 kSPS时的功耗典型值仅为21 mW,100 SPS时仅为21 µW。
The AD7660 is the first of a new generation of 16-bit ADCs, delivering true 16-bit performance at a very low cost. The new generation is based on the Pulsar core, a true breakthrough architecture, that powers the industry's fastest and most accurate SAR ADCs. With no pipeline delay, the AD7660 is ideally suited for industrial process control, multiplexed data acquisition systems, interfacing with DSP chips, portable equipment and medical instrumentation. It boasts 90 dB SINAD, a -96 dB THD @ 10 kHz and DC precision at 16 bits (No Missing Codes). INL is ±3 LSB Max, DNL is 1.75 LSB max. Power dissipation is only 21 mW typical at 100 kSPS, and only 21 µW @ 100 SPS.
