OPA828 Third Generation Super Single Op Amp to Dual Op Amp Board Low Noise HiFi Audio Operational Amplifier Module

OPA828 Third Generation Super Single Op Amp to Dual Op Amp Board Low Noise HiFi Audio Operational Amplifier Module Beskrivelse

The OPA828 is an upgraded version of the OPA627 operational amplifier.


It combines high speed, high precision, and superior AC performance.

It achieves low offset voltage (50µV), low temperature drift (0.45µV/C typical), and low bias current (1pA typical).

It offers low noise (4nV/Hz typical), with a noise level of just 60nVRMS in the 0.1Hz to 10Hz range.

It operates over a wide supply voltage range of 4V to 18V, with a supply current of only 5.5mA per channel.

Note: The OPA828 is not the AD828; it is a chip of a completely different class.

Its sound quality is more transparent and penetrating than the classic high-end OPA627, with a highly refined midrange free of harshness.

An excellent choice for both new equipment builds and audio upgrades.
