Texas Instruments AMC0x02D Precision Reinforced Isolated Amplifier
Texas Instruments AMC0x02D Precision Isolated Amplifier is a galvanically isolated amplifier with a ±50mV differential input and a differential output. This amplifier operates with a supply voltage range of 3V to 5.5V for the high-side (VDD1) and 3V to 5.5V for the low-side (VDD2). The isolation barrier separates parts of the system operating at different common-mode voltage levels and 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 AMC0x02D isolated amplifier comes in 8-pin, wide and narrow-body SOIC packages, and is fully specified over the temperature range from -40°C to 125°C. Typical applications include industrial motor drives, frequency inverters, server Power-Supply Units (PSU), and Power Factor Correction (PFC).
