NTE975 & NTE975SM Integrated Circuit Operational Amplifier Description: The NTE975 and NTE975SM are general purpose operational amplifiers built on a single chip. The resulting close match and tight thermal coupling gives low offsets and temperature drift as well as fast recovery from thermal transients. The unitygain compensation specified makes the circuit stable for all feedback configurations, even with capacitive loads. However, it is possible to optimize compensation for the best high frequency performance at any gain. As a comparator, the output can be clamped at any desired level to make it compatible with logic circuits.

For operating at elevated temperatures the devices must be derated based on a maximum junction to case thermal resistance of +45C/W, or +150C/W junction to ambient. Note 2. For supply voltages less than 15V, the absolute maximum input voltage is equal to the supply voltage. Note 3. Continuous short circuit is allow for ambient temperatures to +70C.Electrical Characteristics: (0 T +70C, 5V V 15V unless otherwise specified) A S Parameter Symbol Test Conditions Min Typ Max Unit Input Offset Voltage V T = +25C, R 10k 1.0 5.0 mV IO A S R 10k 6.0 mV S Input Offset Current I T = +25C 40 200 nA IO A 300 nA Input Bias Current I T = +25C 120 500 nA IB A 0.8 A Input Resistance r T = +25C 300 800 k i A Supply Current I T = +25C, V = 15V 1.8 2.8 mA D A S T = +125C, V = 15V 1.2 2.25 mA A S Large Signal Voltage Gain A T = +25C, V = 15V, 50 160 V/mV v A S V = 10V, R 2k OUT L V = 15V, V = 10V, 25 V/mV S OUT R 2k L TCV R 50 3.0 V/C Average Temperature Coefficient IO S of Input Offset Voltage R 10k 6.0 V/C S Output Voltage Swing V V = 15V, R = 10 12 14 V O S L V = 15V, R = 2k 10 13 V S L Input Voltage Range V V = 15V 12 V ICR S Common Mode Rejection Ratio CMRR R 10k 70 90 dB S Supply Voltage Rejection Ratio PSRR R 10k 77 90 dB S Pin Connection Diagram Compensation 1 8 Compensation Inverting Input 2 7 V (+) NonInverting Input 3 6 Output V () 4 5 Balance
