Unity-Gain Amplifier Figure 8. Noise-Test Circuit 7 Detailed Description 7.1 Overview These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the LM2902 device), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage. Applications include transducer amplifiers, DC amplification blocks, and all the conventional operational-amplifier circuits that now can be more easily implemented in single-supply-voltage systems. For example, the LM124 device can be operated directly from the standard 5-V supply that is used in digital systems and provides the required interface electronics, without requiring additional ±15-V supplies. www.umw-ic.com 7 友台半导体有限公司 UMW R UMW LM124/LM224/2902 Quadruple Operational Amplifiers 7.2 Functional Block Diagram VCC ≈6-µA Current Regulator ≈6-µA Current Regulator ≈100-µA Current Regulator OUT IN− † ≈50-µA Current Regulator IN+ † GND To Other Amplifiers COMPONENT COUNT (total device) Epi-FET Transistors Diodes Resistors Capacitors www.umw-ic.com 8 1 95 4 11 4 友台半导体有限公司 UMW R UMW LM124/LM224/2902 Quadruple Operational Amplifiers PACKAGE SOP14 Q A C1 C B D A1 a 0.25 b UNIT:mm DIM.
