应用功能:Precision, Dual-Channel Difference Amplifier The AD8270 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier(G=0.5, 1, or 2), inverting amplifier (G=0.5, 1, or 2) or noninverting amplifier (G=1.5, 2, or 3).
