Isolation Amplifiers & Isolated Delta - Sigma Modulators

Our isolation amplifier is an optically coupled isolation amplifier with a high-precision ΔΣAD converter on the input side. It is particularly suitable for realizing current sensor and voltage sensor. It achieves the industry's highest level of linearity and has high common-mode transient immunity (CMTI), so it can be operated stably even in motor control applications where high noises are generated.
