SOIC (DWV)-8-67.275 mm² 5.85 x 11.5
The AMC0x36-Q1 is a precision, galvanically isolated delta-sigma (ΔΣ) modulator with a ±1V, high impedance input and external clock. The high-impedance input is optimized for connection to high-impedance resistive dividers or other voltage signal sources with high output resistance.
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. This barrier is certified to provide reinforced isolation up to 5kVRMS (DWV package) and basic isolation up to 3kVRMS (D package) (60s).
The output bitstream of the AMC0x36-Q1 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 39kSPS sample rate.
The AMC0x36-Q1 devices come in 8-pin, wide-and narrow-body SOIC packages, and are fully specified over the temperature range from –40°C to +125°C.
