Improve your design with high-performance isolated ADCs
ADCs with isolation technology that enables higher performance and longer lifetimes
Isolated ADCs, also known as isolated modulators, are ICs that output a digital bitstream from a precise delta sigma modulator capable of withstanding high common mode voltages. TI’s portfolio consists of both basic and reinforced isolated modulators for current sensing and voltage sensing applications needing high performance and reliability at a low price.
