3 Description

The AMC0x36-Q1 is a precision, galvanically

isolated delta-sigma (ΔΣ) modulator with a ±1V,

high impedance input and external clock. The highimpedance

input is optimized for connection to highimpedance

resistive dividers or other voltage signal

sources with high output resistance.

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 AMC0x36-Q1 is

synchronized to an external clock. Combined with

a sinc3, OSR 256 filter, the device achieves 14.8

effective bits of resolution or 89dB of dynamic range,

at a 39kSPS sample rate.

The AMC0x36-Q1 devices come in 8-pin, wide-and

narrow-body SOIC packages, and are fully specified

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