HA-5101
Data Sheet April 2002 FN2905.4
10MHz, Noise, Operational Amplifiers
HA-5101 dielectrically isolated operational amplifier featuring noise, (3.0nV/Hz 1kHz). characteristics HA-5101 assure accurate performance. 0.5mV offset voltage externally adjustable offset voltage drift just 3µV/oC. offset current only 30nA reduces input current errors open loop voltage gain 106V/V increases loop gain distortion amplification. HA-5101 ideal audio applications, especially lowlevel signal amplifiers such microphone, tape head phono cartridge preamplifiers. Additionally, well suited distortion oscillators, noise function generators high filters.

NOTE: Proper decoupling always recommended, 0.1µF high quality capacitor should very near device's supply pins.
Input Protection Offset Adjustment
HA-5101 built-in back-to-back protection diodes which will limit differential input voltage approximately
5101 will used conditions where that voltage exceeded, then current limiting resistors must used. more than 25mA should allowed flow HA-5101's input.
