OPA4196IDR

The OPAx196 series is a new generation of 36V rail-to-rail e-trim™ operational amplifiers. These devices offer very low offset voltage (typ. ±25μV), drift (typ. ±0.5μV/°C), and low bias current (typ. ±5pA) across the entire output range, along with very low quiescent current (typ. 140μA per channel). The OPAx196 features many unique characteristics, such as a differential input voltage range that can reach the supply rails, high output current (±65mA), and the ability to drive high capacitive loads up to 1nF. It is a robust and high-performance operational amplifier suitable for various high-voltage industrial applications. The OPAx196 series operational amplifiers come in standard packages and operate over a rated temperature range of -40°C to +125°C.
