3 Description

The AMC0x06M25 is a precision, galvanically

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

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 AMC0x06M25 is

synchronized to an external clock. Combined with a

sinc3, OSR 256 filter, the device achieves 16 effective

bits of resolution or 88dB of dynamic range, at a

78kSPS sample rate.

The AMC0x06M25 comes in 8-pin, wide- and narrowbody

SOIC packages. The device is fully specified

over the temperature range from –40°C to +125°C.
