The AMC0x06M05-Q1 is a precision, galvanically isolated delta-sigma (ΔΣ) modulator with a ±50mV, differential input and digital output. The input is optimized for connection to low-impedance shunt resistors commonly used for current-sensing applications.
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 AMC0x06M05-Q1 is synchronized to an external clock. Combined with a sinc3, OSR 256 filter, the device achieves 16 effective bits of resolution or 84dB of dynamic range, at a 78kSPS sample rate.
The AMC0x06M05-Q1 comes in 8-pin, wide- and narrow-body SOIC packages. The device is fully specified over the temperature range from –40°C to +125°C.
