The AMP011 is a monolithic instrumentation amplifier designed for high-precision data acquisition and instrumentation applications. The design combines the conventional features of an instrumentation amplifier with a high current output stage. The output remains stable with high capacitance loads (1 μF), a unique ability for an instrumentation amplifier. Consequently, Input offset voltage is very low (20 μV), which generally eliminates the external null potentiometer. Temperature changes have minimal effect on offset; TCVIOS is typically 0.15 μV/°C.
