3 Description
The OPAx196 family (OPA196, OPA2196, and OPA4196) is a new generation of 36-V, rail-to-rail etrim™ operational amplifiers (op amps).
These devices offer very low offset voltage (±25 μV, typical), drift (±0.5 μV/°C, typical), and low bias current (±5 pA, typical) combined with very low quiescent current (140 μA/channel, typical) across th...
