3 Description
The AMC0x03M0510 is a precision, galvanically
isolated delta-sigma (ΔΣ) modulator with a ±50mV
input and internal clock. 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 AMC0x03M0510 is
synchronized to the internally generated 10MHz clock.
Combined with a sinc3, OSR 256 filter, the device
achieves 12.2 effective bits of resolution or 78dB of
dynamic range, at a 39kSPS sample rate.
The AMC0x03M0510 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.
