Overview
ACPL-C797T Automotive Optically Isolated Sigma-Delta Modulator Data Sheet Description The ACPL-C797T is a 1-bit, second-order sigma-delta (Σ-∆) modulator that converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology.
The ACPL-C797T operates from a 5 V power supply with dynamic range of 79 dB with an appropriate digital filter.
The differential inputs of ±200 mV (full scale ±320 mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications such as motor phase current measurement.
The ACPL-C797T isolated modulator converts a lowbandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta (Σ-∆) over-sampling modulator.
The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels.
Combined with superior optical coupling t...
