The OP-41 's cascade input stage boosts CMR to over 100dB, improves CMR linearity, and stabilizes bias current with changing common-mode voltage. The linear common-mode rejection of 100dB min is unusually good for a FET input amplifier. The OP-41 consumes only 750)lA supply current and has a powersupply rejection ratio of 25)lV/V, making it an ideal choice for battery-operated systems. Despite the low supply-drain, the slew-rate is a respectable 1.3V/IlS. and symmetrical Using zener-zap trimming techniques. offset voltage is adjusted to below SOOIlV which eliminates the need for external nulling in many applications. The OP-41's guaranteed gain of 1 million into a 2kH load. combined with the linear 100dB minimum CMR. vastly improves linearity over competitive low-cost devices. Linearity is excellent in both low-gain and high-gain amplifier configurations. In voltage follower applications CMR effects dominate linearity. and in high-gain applications openloop gain dominates linearity, hence the performance advantage of the OP-41.

GENERAL DESCRIPTION EPOXYMINI-DIP (P-Suffix) 8-PINSO (S.Suffix) The OP-41 JFET -input op amp features a SpA max bias current with an open-loop gain of over 1 million. 77° of phase margin provides exceptional stability, even in unity-gain with capacitive loads. The output is guaranteed stable with 2S0pF loads at unity-gain, and will typically drive several thousand pF. Transient response is extremely clean. and is considerably improved over industry-standard JFET amplifiers.
