Highlights:
In order to reduce the possibility of self-excitation of high-speed operational amplifiers, high-quality capacitor-resistor devices are used as far as possible in board layout, and fixed resistors are used instead of sliding rheostats for gain variation. It is easy to cause self-excitation of operational amplifiers. The module adopts fixed resistance mode for gain adjustment, which is stable and reliable, and has good high frequency performance. Because of the AC characteristics of the operational amplifier and the limitation of the gain bandwidth product, the higher the gain of the operational amplifier, the smaller the bandwidth. So when you use amplifier, if the amplification factor is very large, please use multi-stage cascade amplification to meet the bandwidth and gain requirements. If the rear stage needs to be loaded, use a high-speed broadband current buffer. Parameters: Name: THS3061 High Speed Broadband Operational Amplifier High Speed Current Buffer Size: 50mm * 42mm Power supply:±5V~±15V Bandwidth: 300MHz Output Current: ±145mA RL=50Ω Amplifier Type: In-phase Amplifier Package include: module*1 Operational Amplifier Gain, Bandwidth, GBW Common Knowledge: (Selection as Buyer): AC characteristics: When the gain bandwidth product of GBW is 1 kHz and amplified 128 times, the margin of GBW > 128kHz in practical application is 10-100 times. GBW should be greater than 5 MHz. AC characteristics: Voltage swing rate MAX voltage 25.6Vpp, 1kHz SR=2πVpkf=2*3.14*25.6v*1KHz=0.16V/μs AS practical application leave 10-100 times margin, so 2V/μs should be chosen. To sum up: Vs > 30V, Vos < 1mV, GBW > 5Mhz, SR > 2V/μs Options: OPA227, OPA209, OPA211Elecdemonded in 2015 , Elecdemo is a well-established technology company that integrates supply , R & D , prodund sales , supporting agents , franchises , customization and bulk purchases .
