WebDescripción de INA148. The INA148 is a precision, low-power, unity-gain difference amplifier with a high common-mode input voltage range. It consists of a monolithic precision bipolar op amp with a thin-film resistor network. The on-chip resistors are laser trimmed for an accurate 1V/V differential gain and high common-mode rejection. WebGain nonlinearity cannot be trimmed; it is a function of careful design and die layout. The use of common centroid geometries and iso-thermal layout cancels the errors due to die stress and thermal gradients. If this is not done correctly, all the trimming in the world will not improve performance. Input Protection
