HA-5101
FN2905.4
10MHz, Low Noise, Operational Amplifiers
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 adjust-
able 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 low-
level 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.
