The HA-5101 is a dielectrically isolated operational amplifier featuring low noise, (3.0nV/√Hz at 1kHz).
DC characteristics of the HA-5101 assure accurate performance. The 0.5mV offset voltage is externally adjustable and offset voltage drift is just 3µV/oC. An offset current of only 30nA reduces input current errors and an open loop voltage gain of 1 x 106V/V increases loop gain for low distortion amplification.
