HA-5101/883
Low Noise, High Performance Operational
Amplifier
The HA-5101/883 is a dielectrically isolated operational
amplifier featuring low noise and high performance. This
amplifier has an excellent noise voltage density of
4.5nV/√Hz (max) at 1kHz. The unity gain stable
HA-5101/883 yields a 10MHz unity gain bandwidth and a
6V/µs slew rate.
DC characteristics of the HA-5101/883 assure accurate
performance. The 3mV (max) offset voltage is externally
adjustable and offset voltage drift is just 3µV/°C. Low bias
currents (200nA max) reduce input current errors and the
high open loop voltage gain of 100kV/V, over temperature,
increases the loop gain for low distortion amplification.
The HA-5101/883 is ideal for audio applications, especially
low-level signal amplifiers such as microphone, tape head
and preamplifiers. Additionally, it is well suited for low
distortion oscillators, low noise function generators and high
Q filters.
