NTE894M & NTE894SM Integrated Circuit Low Noise Operational Amplifier Description: The NTE894M and NTE894SM are single, high performance, low noise operational amplifiers. Compared to other operational amplifier, these devices show better noise performance, improved output drive capability and considerably higher small signal and power bandwidths. This makes the devices especially suitable for applications in high quality and professional audio equipment, in instrumentation and control circuits and telephone channel amplifiers. The OP amps are internally compensated for gain equal to, or higher than, three. Features: Small Signal Bandwidth Large Supply Voltage Range Available in 8 Lead Mini DIP (NTE894M) and Surface Mount SOIC 8 (NTE894SM) Applications: Audio Equipment Instrumentation and Control Circuits Telephone Channel Amplifiers Medical Equipment Absolute Maximum Ratings: Supply Voltage, V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22V S Differential Input Voltage (Note 1), V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.5V DIFF Input Voltage, V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Diodes protect the inputs against over voltage. Therefore, unless current limiting resistors are used, large currents will flow if the differential input voltage exceeds 0.6V. maximum cur- rent should be limited to 10mA. Note 2. For operation at elevated temperature, derate packages based on the following junctionto ambient thermal resistance: NTE894M 105C/W NTE894SM 160C/W. Note 3. Output may be shorted to GND at V = 15V, T = +25C. Temperature and/or supply voltages S A must be limited to ensure dissipation rating is not exceeded.DC Electrical Characteristics: (T = +25C, V = 15V, unless otherwise specified) A S Parameter Symbol Test Conditions Min Typ Max Unit Input Offset Voltage V 0.5 4 mV OS T = 0 to +70C 5 mV A V /T 5 V/C OS Input Offset Current I 20 300 nA OS T = 0 to +70C 400 nA A I /T 200 pA/C OS Input Bias Current I 500 1500 nA B T = 0 to +70C 2000 nA A I /T 5 nA/C B Supply Current I 4 8 mA CC T = 0 to +70C 10 mA A Input CommonMode Range V 12 13 V CM CommonMode Rejection Ratio CMRR 70 100 dB Power Supply Rejection Ratio PSRR 10 100 V/V LargeSignal Voltage Gain A R 600, V = 10V 25 100 V/mV VOL L O T = 0 to +70C 15 V/mV A Output Voltage Swing V R 600 12 13 V OUT L T = 0 to +70C 10 12 V A R 600, V = 18V 15 16 V L O R 2k 13 13.5 V L T = 0 to +70C 12 12.5 V A Input Resistance R 50 100 k IN Output ShortCircuit Current I 38 mA SC AC Electrical Characteristics: (T = +25C, V = 15V unless otherwise specified) A S Parameter Symbol Test Conditions Min Typ Max Unit Output Resistance R A = 30dB, ClosedLoop, f = 10kHz, R = 600, 0.3 OUT V L C = 22pF C Transient Response Voltage Follower, V = 50mV, R = 600, IN L C = 22pF, C = 100pF C L Rise Time t 20 ns R Overshoot 20 % Transient Response V = 50mV, R = 600, C = 47pF, C = 500pF IN L C L Rise Time t 50 ns R Overshoot 35 % Gain A f = 10kHz, C = 0 6 V/mV V C f = 10kHz, C = 22pF 2.2 V/mV C Gain Bandwidth Product GBW C = 22pF, C = 100pF 10 MHz C L Slew Rate SR C = 0 13 V/s C C = 22pF 6 V/s C Power Bandwidth V = 10V, C = 0 200 kHz OUT C V = 10V, C = 22pF 95 kHz OUT C V = 14V, R = 600, C = 22pF, V = 18V 70 kHz OUT L C CC
