OPA828 JFET-Input Operational Amplifiers

The OPA828 and OPA2828 (OPAx828) JFET input operational amplifiers are the next generation OPA627 and OPA827, combining high speed with high dc precision and ac performance. These op amps supply low offset voltage, low drift over temperature, low bias current, and low noise with only 60-nVRMS 0.1-H.

OPA828 Features

* Low input voltage noise density: 4 nV/√Hz at 1 kHz

* Input voltage noise: 0.1 Hz to 10 Hz: 60 nVRMS

* Low input bias current:

* 0.1 pA (DGN)

* 1 pA (D)

* Input offset voltage:

* 25 μV (DGN)

* 50 μV (D)

* Input offset drift:
