Applications
* Bias current, noise, voltage offset, drift, open-loop gain, common-mode rejection and power supply rejection are superior to BIFET and CMOS amplifiers. Difet fabrication achieves extremely low input bias currents without compromising input voltage noise performance. Low input bias current is mainta
