带DSP的6输入通道模拟前端

AD73460是一款面向工业电能计量或多通道模拟输入等通用应用的6输入通道模拟前端处理器。配有6个16位A/D转换通道，在直流至2 kHz信号带宽下，各通道均可实现72 dB的信噪比。每个通道还集成一个可编程输入增益放大器(PGA)，增益设置分为8级：从0 dB至38 dB。AD73460特别适用于工业电能计量，因为各通道同时进行采样，可确保转换间不存在（相位）延迟。AD73460全部通道均支持低群延迟转换，片内集成1.25V的基准电压。同时，用户也可以通过编程将采样率设置为64 kHz、32 kHz、16 kHz和8 kHz四种采样率（主时钟频率为16.384 MHz）；而借助串行端口（SP • 6个16位A/D转换器\n\n• 可编程输入采样率（8 kSPS、16 kSPS、32 kSPS、64 kSPS）\n\n• 同步采样\n\n• 信噪比：72 dB\n\n• 串扰：-80 dB\n\n• 低群延迟（典型值：25 µs/ADC通道）\n\n• 可编程输入增益\n\n• 单电源工作\n\n\n\n• 片内基准电源\n\n• 指令周期时间：19 ns（3.3 V、52 MIPS持续性能）\n\n• 单循环指令执行\n\n• 单循环内容切换\n\n• 借助3总线架构，可在每个指令周期中实现双取操作数\n\n• 多功能指令\n\n• 省电模式：低功耗CMOS待机\n\n• 功耗低：;
