LM747 LM747 Dual Operational Amplifier Literature Number: SNOS661 LM747 Dual Operational Amplifier General Description Features The LM747 is a general purpose dual operational amplifier. The two amplifiers share a common bias network and power supply leads. Otherwise, their operation is completely independent. Additional features of the LM747 are: no latch-up when input common mode range is exceeded, freedom from oscillations, and package flexibility. The LM747C/LM747E is identical to the LM747/LM747A except that the LM747C/LM747E has its specifications guaranteed over the temperature range from 0§ C to a 70§ C instead of b55§ C to a 125§ C. Y Y Y Y Y Y No frequency compensation required Short-circuit protection Wide common-mode and differential voltage ranges Low power consumption No latch-up Balanced offset null Connection Diagrams Dual-In-Line Package Metal Can Package TL/H/11479 – 5 TL/H/11479 – 4 Order Number LM747H See NS Package Number H10C Order Number LM747CN or LM747EN See NS Package Number N14A *V a A and V a B are internally connected.

For operating at elevated temperatures, devies in the TO-5 package must be derated based on a thermal resistance of 150§ C/W, junction to ambient, or 45§ C/W, junction to case. The thermal resistance of the dual-in-line package is 100§ C/ W, junction to ambient. Note 2: For supply voltages less than g 15V, the absolute maximum input voltage is equal to the supply voltage. Note 3: These specifications apply for g 5V s VS s g 20V and b 55§ C s TA s 125§ C for the LM747A and 0§ C s TA s 70§ C for the LM747E unless otherwise specified. The LM747 and LM747C are specified for VS e g 15V and b 55§ C s TA s 125§ C and 0§ C s TA s 70§ C, respectively, unless otherwise specified. Note 4: Calculated value from: 0.35/Rise Time (ms).
