3 Description

The OPAx196 family (OPA196, OPA2196, and OPA4196) is a new generation of 36-V, rail-to-rail e-trim™ 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 the entire output range.

Unique features, such as differential input-voltage range to the supply rail, high output current (±65 mA), and high capacitive load drive of up to 1 nF make the OPAx196 a robust, high-performance operational amplifier for high-voltage industrial applications.

The OPAx196 family of op amps is available in standard packages and is specified from –40°C to +125°C.
