LT1809

The new LT1806 and LT1809 are fast operational amplifiers with rail-to-rail inputs and outputs. The LT1806 is optimized for low noise (3.5nV/Hz)image) and offset (100μV typical, 550μV max) and has a 325MHz gain bandwidth product. The LT1809 is optimized for low distortion (−90dBc to 5MHz) and has a 180MHz gain bandwidth product. Both amplifiers have 85mA output drive capability and are fully specified ...
