The CS5376A is a multi-function digital filter utilizing a low-power signal processing architecture to achieve efficient filtering for up to four modulators. By combining the CS5376A with CS3301/02 differential amplifiers,CS5371/72 modulators, and the CS4373 test DAC a synchronous high resolution multi-channel measurement system can be designed quickly and easily.
Digital filter coefficients for the CS5376A FIR and IIR filters are included on-chip for a simple setup, or they can be programmed for custom applications. Selectable digital filter decimation ratios produce output word rates from 4000SPS to 1SPS, resulting in measurement bandwidths ranging from 1600Hz down to 400mHz when using the on-chip coefficient sets.The CS5376A includes integrated peripherals to simplify system design: offset and gain corrections, a test DAC bit stream generator, a time break controller, 12 general purpose I/O pins, a secondary SPI port, and a boundary scan JTAG port.
