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.
