Super OP AMP OPA828 For Audio Amplifier IC Fever Dual Operational Amplifier SOP8 SOIC8 Single IC Better More AD828

Opa828 JFET is an upgraded version of opa627 operational amplifier, which integrates high speed, high DC precision and high AC performance. The operational amplifier can realize low offset voltage (50 µ V), low temperature drift (0.45 µ V / ° C typical value), low bias current (1pA typical value) and low noise (4nv / √ Hz typical value). The noise is only 60nvrms 0.1Hz to 10Hz. Opa828 operates in a wide supply voltage range of ± 4V to ± 18V, and the supply current of each is only 5.5ma (typical value).

***Note that opa828 is not ad828. It comes from chips of different grades.

The sound quality is more nsparent than the claic high-end opa627. It is very peneting, and the medium frequency is also very delicate without burr. It is very worthy of new machines and grinding machines

The switching operational amplifiers are made of German silver solder to ensure sound quality, and the pins are gold-plated pins

The SMD to in-line single operational amplifier version can be upgraded to ne5534, opa627, opa604, lme49710, ad797, etc

The SMD to in-line dual operational amplifier version can be upgraded to ne5532, muse920, opa2604, lme49720, op275, ad827, etc
