The AMC0380R-Q1 is a precision, galvanically isolated amplifier with a high-voltage AC, high-impedance input and single-ended ratiometric output. The input is designed to connect directly to a high-voltage signal source.
The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference and is certified to provide reinforced isolation up to 5kVRMS (60s).
The AMC0380R-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 output of the AMC0380R-Q1 is designed to connect directly to the input of an ADC. Connect REFIN to the same reference voltage as the ADC to match the dynamic input voltage range of the ADC.
The AMC0380R-Q1 is available in two linear input voltage ranges: ±400 and ±600V. With an integrated precision resistive divider, the AMC0380R-Q1 achieves better than 1% accuracy over the full temperature range, including lifetime drift.
The AMC0380R-Q1 is available in a 15-pin, 0.65mm pitch SSOP package. The device is fully specified over the temperature range from –40°C to +125°C.
