The AMC0386 is a precision, galvanically isolated delta-sigma (ΔΣ) modulator with a high-voltage, high impedance input, and external clock. 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 of up to 5kVRMS (60s).
The output bitstream of the AMC0386 is synchronized to an external clock. Combined with a sinc3, OSR 256 filter, the device achieves 14.8 effective bits of resolution or 89dB of dynamic range, at a sample rate of 39kSPS.
With the integrated resistive divider, excellent DC accuracy, low temperature drift and high stability, the AMC0386 achieves better than 1% accuracy over lifetime and temperature without system-level calibration.
The AMC0386 is available in a 15-pin, 0.65mm pitch SSOP package and is fully specified over the temperature range from –40°C to +125°C.
