3 Description
The AMC0x06M05 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 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 comes in 8-pin, wide- and narrowbody
SOIC packages. The device is fully specified
over the temperature range from –40°C to +125°C.
