All voltage values, except differential voltages, are with respect to the midpoint between V + and V . CC CC Note 2. Differential voltages are at the noninverting input pin with respect to the inverting input pin. Note 3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15V, whchever is less. Note 4. The output may be shorted to GND or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.Electrical Characteristics: (V = 15V, Note 5 unless otherwise specified) CC Parameter Symbol Test Conditions Min Typ Max Unit Input Offset Voltage V V = 0, T = +25C 3 15 mV IO A O R = 50 S T = 0 to +70C 20 mV A Temperature Coefficient of V = 0, R = 50 , T = 0 to +70C 10 V/C VIO O S A Input Offset Voltage Input Offset Current I V = 0, Note 6 T = +25C 5 200 pA IO O A T = 0 to +70C 5 nA A Input Bias Current I V = 0, Note 6 T = +25C 30 400 pA IB O A T = 0 to +70C 10 nA A 12 CommonMode Input Voltage Range V T = +25C 11 V ICR A +15 Maximim Peak Output Voltage Swing V R = 10k , T = +25C 10.0 13.5 V OM L A R 10k , T = 0 to +70C 10.0 V L A A T = +25C 3 6 V/mV LargeSignal Differential Voltage V = 10V, VD A O Amplification R 10k L T = 0 to +70C 3 V/mV A UnityGain Bandwidth B R = 10k , T = +25C 1 MHz 1 L A 12 Input Resistance r T = +25C 10 i A CommonMode Rejection Ratio CMRR V = V min, V = 0, R = 50 , 70 86 dB IC ICR O S T = +25C A Supply Volatge Rejection Ratio k V = 15V to 9V, V = 0, 70 95 dB SVR CC O ( V / V ) R = 50 , T = +25C CC IO S A Total Power Dissipation P No Load, V = 0, T = +25C 6.0 7.5 mW D O A Supply Current I No Load, V = 0, T = +25C 200 250 A CC O A Crosstalk Attenuation V /V A = 100, T = +25C 120 dB o1 o2 VD A Note 5. All characteristics are measured under openloop conditions with zero commonmode volt- age unless otherwise specified. Note 6. Input bias currents of a FETinput operational amplifier are normal junction reverse currents, which are temperature sensitive. Pulse techniques must be used that will maintain the junc- tion temperature as close to the ambient temperature as possible.
