3 Description
The AMC0x11R-Q1 is a precision, galvanically
isolated amplifier with a 2.25V, high impedance
input and single-ended ratiometric output. The highimpedance
input is optimized for connection to a highimpedance
resistive divider or other voltage signal
source 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 AMC0x11R-Q1 outputs a single-ended signal
proportional to the input voltage. The full-scale output
is set by the voltage applied to the REFIN pin. The
output of the AMC0x11R-Q1 is designed to connect
directly to the input of an ADC. Connect REFIN to
the same reference voltage as the ADC to match the
dynamic input voltage range of the ADC.
The AMC0x11R-Q1 comes in 8-pin, wide- and
narrow-body SOIC packages, and is fully specified
over the temperature range from –40°C to +125°C.
