Description

The CS5376A is a multi-function digital filter utilizing a low-power signal processing architecture to achieve efficient filtering for up to four ∆Σ modulators. By combining the CS5376A with CS3301A/02A differential amplifiers, CS5371A/72A ∆Σ modulators, and the CS4373A ∆Σ test DAC a synchronous, high-resolution, self-testing, 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 4000 SPS to 1 SPS, resulting in measurement bandwidths ranging from 1600 Hz down to 400 mHz when using the on-chip coefficient sets.
