3 Description

The AMC0x03M2510 is a precision, galvanically

isolated delta-sigma (ΔΣ) modulator with a ±250mV

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 AMC0x03M2510 is

synchronized to the internally generated 10MHz clock.

Combined with a sinc3, OSR 256 filter, the device

achieves 12.8 effective bits of resolution or 80dB of

dynamic range, at a 39kSPS sample rate.

The AMC0x03M2510 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.
