AMC1350DWVR

The AMC1350DWVR from Texas Instruments is a precision, reinforced isolated amplifier. It provides an output separated from the input circuitry by an isolation barrier highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation up to 5 kV RMS according to VDE V 0884-11 and UL1577, supporting a working voltage of up to 1.5 kV RMS.

The high-impedance input is optimized for connection to high-impedance resistive dividers or other voltage signal sources with high output resistance. Key electrical specifications include a linear input voltage range of ±5 V, a high input impedance of 1.25 MΩ (typ), and a fixed gain of 0.4 V/V. It offers low DC errors with an offset error of ±1.5 mV (max) and an offset drift of ±15 µV/°C (max).

This isolated amplifier operates on 3.3 V or 5 V and boasts high Common Mode Transient Immunity (CMTI) of 100 kV/µs (min). It is fully specified over the extended industrial temperature range of -40°C to +125°C. The device is housed in an 8-pin SOIC package suitable for surface mounting.

Safety-related certifications include 7070-V PK reinforced isolation per DIN VDE V 0884-11:2017-01 and 5000-V RMS isolation for 1 minute per UL1577. The AMC1350DWVR is designed to protect low-voltage circuitry from potentially harmful voltages and damage by separating system parts operating on different common-mode voltage levels.
