The CS5376 is a multi-function digital filter utilizing a low-
power signal processing architecture to achieve efficient
filtering for up to four ∆−Σ modulators. Used in combina-
tion with the CS5371 and CS5372 ∆−Σ modulators, a
unique high resolution A/D measurement system results.
Digital filter coefficients for the CS5376 FIR and IIR filters
can be programmed for custom applications, or the on-
chip coefficient set can be used for a simple setup. Filter
configuration is initialized through a serial port using a
microcontroller or a configuration EEPROM.
The CS5376 includes a test bit stream generator that
produces a 1-bit ∆−Σ modulated output suitable for driv-
ing a test DAC. It also includes 12 general purpose I/O
pins for local hardware control, a secondary master
mode SPI port to communicate with serial peripherals,
and an IEEE 1149.1 JTAG test port for boundary scan.
