NTE948 & NTE948SM Integrated Circuit Quad Operational Amplifier Description: The NTE948 (14Lead DIP) and NTE948SM (SOIC14) consists of four independent, high gain, in- ternally compensated, low power operational amplifiers which have been designed to provide func- tional characteristics identical to those of the familiar 741 operational amplifier. Features: Low Supply Current Drain Class AB Output Stage No Crossover Distortion Low Input Offset Voltage Low Input Offset Current Low Input Bias Current High Degree of Isolation Between Amplifiers Overload Protection for Inputs and Outputs Available in 14Lead DIP (NTE948) and Surface Mount (NTE948SM) Absolute Maximum Ratings: Supply Voltage, V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V S Differential Input Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Output Short Circuit Duration (Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Any of the amplifier outputs can be shorted to ground indefinitely however, more than one should not be simultaneously shorted as the maximum junction temperature will be exceeded. Note 2. The maximum power dissipation for these devices must be derated at elevated tempera- tures and is dicated by T R , and the ambient temperature, T . The maximum avail- J(MAX), thJA A able power dissipation at any temperature is P = (T T )/R or the 25C P , D J(MAX) A thJA D(MAX) which ever is less.Electrical Characteristics: (V = 15V, 0 T +70C unless otherwise specified) S A Parameter Test Conditions Min Typ Max Unit Input Offset Voltage T = +25C, R 10k 1.0 6.0 mV A S R 10k 7.5 mV S Input Offset Current T = +25C 4 50 nA A 100 nA Input Bias Current T = +25C 30 200 nA A 400 nA Input Resistance T = +25C 0.8 2.5 M A Supply Current, All Amplifiers T = +25C, V = 15V 2.4 4.5 mA A S Large Signal Voltage Gain T = +25C, V = 15V, V = 10V, R 2k 25 160 V/mV A S OUT L V = 15V, V = 10V, R > 2k 15 V/mV S OUT L AmplifiertoAmplifier Coupling T = +25C, f = 1Hz to 20kHz 120 dB A SmallSignal Bandwidth T = +25C 1.0 MHz A Phase Margin T = +25C, A = 1 60 degrees A V Slew Rate T = +25C, A = 1 0.5 V/ s A V Output ShortCircuit Current T = +25C 25 mA A Output Voltage Swing V = 15V, R = 10k 12 13 V S L V = 15V, R = 2k 10 12 V S L Input Voltage Range V = 15V 12 V S CommonMode Rejection Ratio R 10k 70 90 dB S Supply Voltage Rejection Ratio R 10k , 5V V 15V 77 96 dB S S Pin Connection Diagram Output A 1 14 Output D Invert Input A 2 13 Invert Input D NonInvert Input A 3 12 NonInvert Input D V (+) 4 11 V () 5 NonInvert Input B 10 NonInvert Input C Invert Input B 6 9 Invert Input C Output B 7 8 Output C
