Texas Instruments AMC0381D Reinforced Isolated Amplifiers are precision, galvanically isolated amplifiers with a high-voltage DC, high impedance input, and a fixed-gain differential output. The input is designed to connect directly to a high-voltage signal source. The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is certified to provide reinforced isolation of up to 5kVRMS (60s) and is highly resistant to magnetic interference. The Texas Instruments AMC0381D outputs a differential signal proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances. The AMC0381D is available in three linear input voltage ranges: 600V, 1000V, and 1600V. With an integrated precision resistive divider, the AMC0381D achieves better than 1% accuracy over the full temperature range, including lifetime drift. The AMC0381D is available in a 15-pin, 0.65mm pitch SSOP package. The device is fully specified over the temperature range from –40°C to +125°C.
