Texas Instruments AMC030xR Isolated Amplifiers

Texas Instruments AMC030xR Isolated Amplifiers are precision, galvanically isolated amplifiers with a ±250mV, differential input and single-ended, ratiometric output. These amplifiers have an input optimized for direct connection to a shunt resistor or other low-impedance signal source. The AMC030xR amplifier's output is designed to connect directly to the ADC input. These amplifiers operate over the temperature range from -40°C to 125°C. The AMC030xR amplifiers are available in 8-pin wide- and narrow-body SOIC packages. These isolated amplifiers are ideal for industrial motor drives, frequency inverters, server Power Supply Units (PSU), and Power Factor Correction (PFC).
