The HA-5101/883 is a low noise, high performance operational amplifier. It features 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. The HA-5101/883's DC characteristics 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.
