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 3

µV/°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.
