The LH0044 Series is a low noise, ultra-stable, high gain, precision operational amplifier family intended to replace either chopper-stabilized monolithic or modular amplifiers. The devices are particularly suited for differential mode, inverting, and non-inverting mode applications requiring very low initial offset. Low offset drift, very high gain, high CMRR, and high PSRR. In addition, the LH0044 Series’ low initial offset and offset drift eliminate costly and time consuming null adjustments at the systems level. The superior performance afforded by the H0044 Series is made possible by advanced processing and testing techniques, as well as active laser trim of critical metal film resistors to minimize offset voltage and drift.
