Texas Instruments AMC0381R/-Q1 Reinforced Isolated Amplifiers offer high-voltage DC input, high-impedance input, and single-ended ratiometric output. The input is devised to connect directly to a high-voltage signal source. The isolation barrier divides parts of the system that function on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference and is certified to deliver reinforced isolation up to 5kVRMS (60s). The AMC0381R/-Q1 outputs a single-ended signal proportional to the input voltage. The full-scale output is set by the voltage applied to the REFIN pin. The AMC0381R-Q1 is developed to connect directly to the ADC input. Users can connect the REFIN to the same reference voltage as the ADC to match the ADC's dynamic input voltage range.
