Boardoza AMC1350 Isolated Analog Amplifier Breakout Board

Name: Boardoza AMC1350 Isolated Analog Amplifier Breakout Board
Brand: Boardoza
SKU: B1101V10000112

The AMC1350 is a precision, isolated amplifier with an output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE V 0884-11 and UL1577, and supports a working voltage of up to 1.5 kVRMS. The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from potentially harmful voltages and damage.

The high-impedance input of the AMC1350 is optimized for connection to high-impedance resistive dividers or other voltage signal sources with high output resistance. The excellent accuracy and low temperature drift supports accurate AC and DC voltage sensing in DC/DC converters, frequency inverters, AC motor, and servo-drive applications over the extended industrial temperature range from –40°C to +125°C.Linear input voltage range: ±5 V and output range : ±2 V
