AvailableInDieForm 77°Typ 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 SOOIlVwhich eliminates the need for external nulling in ORDERING INFORMATION t =...
