Brief Introduction

The AMC0311SDWVR is a precise electrically isolated amplifier featuring a 2.25V high-impedance input, fixed gain and single-ended output. The high-impedance input is optimized for connections with high-impedance resistor voltage dividers or other voltage signal sources with high output resistance.

The isolation barrier separates the system devices operating at different common-mode voltage levels. This isolation fence has extremely strong anti-electromagnetic interference performance. This isolation barrier is certified to provide an enhanced isolation of up to 5kVRMS (DWV package) and a basic isolation of up to 3kVRMS (D package) (60s).

The AMC0311SDWVR is a single-ended signal proportional to the input voltage, with a fixed gain of 1V/V. The output is designed to be directly connected to the input terminal of the ADC. The voltage applied to the REFIN pin determines the output voltage at the 0V input terminal.

The AMC0311SDWVR device is available in 8-pin, wide-body and narrow-body SOIC packages, with a rated temperature range of -40 °C to +105°C.
