The AMC0386-Q1 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-Q1 is synchronized to the internally generated 10MHz clock. Combined with a sinc3, OSR 256 filter, the device achieves 14.8 effective bits of resolution or 89dB of dynamic range, at a 39kSPS sample rate.
With the integrated resistive divider, excellent DC accuracy, low temperature drift and high stability, the AMC0386-Q1 achieves better than 1% accuracy over lifetime and temperature without system-level calibration.
The AMC0386-Q1 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.
