数字25MHz32nd3V ~ 5.5V

Overview

The Broadcom® ACPL-0873-500E is a 3-channel digital filter designed specifically for Second Order Sigma-Delta Modulators in voltage and current sensing. Each input channel can receive an independent Sigma-Delta (Σ-Δ) modulator bit stream. The bit streams are processed by three individualdigital decimation filters. Features of the digital filter include four decimation ratios for Sinc2 mode and three decimation ratios for Sinc3 mode, offset calibration, and fast over-range detection.The ACPL-0873-500E outputs an over-current signal for three channels, signaling over-voltage/current conditions. Through SPI compatible interface, ACPL-0873-500E can directly connect to a microcontroller to output 16 bits digital filter data and write/read filter registers.
