ACPL-C799 optically isolated sigma-delta modulator
The Broadcom ACPL-C799 is a 1-bit, second-order sigma-delta (Σ-Δ) modulator that converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology. The differential inputs of ±50 mV (full scale ±80 mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications such as motor phase current measurement.
- 77 dB SNR typ
- 1.3 μV/°C maximum offset drift
- 10 MHz internal clock
- 1-bit, second-order sigma-delta modulator
