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. The HA-5101 is ideal for audio applications, especially lowlevel signal amplifiers such as microphone, tape head and phono cartridge preamplifiers. Additionally, it is well suited for low distortion oscillators, low noise function generators and high Q filters.
