Instructions

EL2045 is a low -power 100MHz gain. Based on ELANTEC's high -speed, low -power, low -cost single -chip operations amplifiers exclusively, low -power, and low -cost single -chip operations. The gain of EL2045 is -2 stability, with a conversion rate of 275V/microsecond and a 100MHz gain bandwidth, the gain is -2, and only a power current of 5.2mA is required.

The power supply range of EL2045 is ± 18V to ± 2V. For a single power supply, the working range of EL2045 is 36V to 2.5V. The excellent power supply range of EL2045 makes it a clear choice of applications on single+5V or+3V power supply.

EL2045It also has a very wide output voltage swing amplitude ± 13.6V, VS ± 15V and RL 1kΩ. At ± 5V, the output voltage swing is wide ± 3.8V (RL 500Ω) and ± 3.2V (RL 150Ω). In addition, when a single supply work is+5V, the output voltage fluctuates between 0.3V and 3.8V, RL 500Ω. When the gain is +2, the EL2045 has a -3DB bandwidth of 100MHz, and the phase margin is 50 °. Due to its traditional voltage feedback topology, EL2045 allows useless or non -linear component networks in its feedback. This multifunctional combination of low -cost and 75 mAh output current drive makes EL2045 an ideal price -sensitive application requires low power and high speed.

EL2045 is a low -power broadband gain stable single -chip operational amplifier based on ELANTEC's proprietary high -speed complementary bipolar process. EL2045 uses a classic voltage feedback topological structure, so that it can be used in various applications that are not suitable for current feedback amplifiers because the feedback elements used with the amplifier are limited. For example, the traditional topology of EL2045 allows the capacitor to place the capacitor in the feedback path to make it an excellent choice for the application of active filter, sampling holder or integral device. Similarly, due to the ability to use diode in the feedback network, EL2045 is an excellent choice such as fast -to -number amplifier and other applications.

Single power operation

EL2045 is designed to have a wide range of input and output voltage range. This design also makes EL2045 the best choice for single power operations. With a single positive power supply, the lower input voltage range is within 100 millivolo (RL 500Ω), and the lower output voltage range is within 300 millivolves. The input voltage range reaches 4.2V, the output voltage range reaches 3.8V, and the power supply is 5V, RL 500Ω. This will cause a 3.5V output swing on a single 5V power supply. This wide output voltage range also allows a single power supply to work, and the power supply voltage is as high as 36V or as low as 2.5V. On a single 2.5V power supply, EL2045 still has a 1V output width.

gain bandwidth and -3DB bandwidth

The gain bandwidth of EL2045 is 100MHz, while only 5.2mA power current is used. When the gain is greater than 4, its closed -loop 3DB bandwidth is equal to the gain bandwidth to except the circuit noise gain. For the gain of less than 4, the high -level pole point in the amplifier transmission function will lead to higher closed -loop bandwidth. For example, the bandwidth of EL2045 is -3DB, the gain is 100MHz at +2, and the gain is reduced to 20MHz when the gain is +5. It should be noted that the design of the EL2045 makes this extra " bandwidth in low -gain applications will not be at the expense of stability. As shown in the typical performance curve
