6SDI(Sigma-Delta A/Ds to 220K Samples/ Sec per Channel (Precise Instrumentation/ Wideband Audio))
The 6-channel PMC-6SDI analog input board provides six precision 16-bit Sigma-Delta analog inputs, and requires no external antialiasing filters. Optimized for flexibility and performance, the board is ideal for a wide variety of applications, ranging from simple precision voltage measurements, to the analysis of complex audio signals and waveforms. A FIFO buffer holds up to 64K channel-tagged input samples. Each of the six sigma-delta analog input channels can be controlled by either of two independent sample clocks, and multiple channels can be harmonically locked together. Sample rates are adjustable from 5 KSPS to 220 KSPS per channel, for a maximum aggregate rate of 1320 KSPS, and the input range is software selectable as ±1.25V, ±2.5V, ±5V or ±10V.
