Si894x Isolated Delta-Sigma Modulators

Skyworks Solutions Inc. Si894x Isolated Delta-Sigma Modulators are galvanically isolated modulators that output a digital signal proportional to the voltage level at the input. These delta-sigma modulators are designed for low-voltage and differential signals. This is ideal for connection to low-resistance current shunt measurement resistors. The Si8941A/46A/47A modulators feature a specified full-scale input range of ±62.5mV, whereas the Si8941B/46B/47B devices feature a specified full-scale input range of ±250mV. This allows the user to choose low-ohmic resistance value sense resistors to minimize system power loss.
