ACPL-0873 3-Channel Digital Filters

Broadcom ACPL-0873 3-Channel Digital Filters are designed specifically for second-order sigma-delta modulators in voltage and current sensing. The individual input channels receive an independent Sigma-Delta (Σ-Δ) modulator bit stream, which is processed by three individual digital decimation filters. The digital filters feature four decimation ratios for Sinc2 mode and three decimation ratios for Sinc3 mode, offset calibration, and fast over-range detection.
