HCPL-7860

ADCs/DACs - Special Purpose Overview

The HCPL-7860 is a single-channel, isolated Sigma-Delta modulator manufactured by Broadcom Limited. It provides 15-bit resolution with a fixed 5 V supply voltage and operates within a temperature range of -40°C to +85°C. The device utilizes an SMD-8 Gull Wing package for surface mount installation. As a specialized data acquisition component, it converts low-bandwidth analog inputs into high-speed one-bit digital streams via over-sampling modulation. This architecture ensures high noise immunity and robust isolation performance for precision measurement applications.
