• AD8033 distortion

    Hello.

    I have a circuit with an AD8033 in voltage follower topology (gain=1), with Vs+=24V, Vs-=0V (GND).

    The input signal is a positive sine of 10Vpp.

    In figure 1, at frequency 100kHz, the output (blue) follows the input (yellow).

  • RE: AD8033, bipolar mode switching

    Hi,

    Figure 53 of the data sheet shows the simplified Input Stage of AD8033/34.

    There are two input stages; the JFET input and the Bipolar Input.

    The Input Overdrive Section discussed how the transition occurs between these two input stages and this is…

  • AD8033 - Input voltage range

    Question for you:

    AD8033

    I’m a bit confused with the Common Mode Input characteristics under Vs:+ 5V è

    è FYI, Our application is +5V single supply.

    The Input Common Voltage Range is specified 0 – 2 V while…

  • 有关AD8033和8066滤波电路带宽

    如题,自己仿真了一放大电路,但没弄明白仿真出来的结果。以下的电路图中,施加电流信号,仿真得到带宽为59MHz,增益为820。增益这么大理解,但带宽这么大就搞不懂了。。。  我也网上查过,AD8033在增益为1时,带宽为80MHz。

    后来我又采用两级运放放大,得到的带宽只有5.42MHz,增益为82.6,如下图。

                                                 所以想到论坛里发帖问问, 运放设计这些问题。

  • RE: AD8034

    Hello,

    This is a good question, the AD8034 is a dual FET input amplifier. The AD8033 is the single version, we typically dont build dual Spice models, we just use two AD8033 Spice models to get a AD8034. For your application I would recommend just using…

  • RE: 50MHZ BW Instrumentation amplifier

    Need high CMRR as well. I am using AD8033 as the front end, need a fast difference amplifier with at least +-7.5 voltage so I don't have to match the resistors. You need to have laser trimmed resistor in the difference amplifier. 

  • RE: 关于噪声的11个误区,你陷在哪一个?

    在电路中,噪声经常是各位工程师需要考虑的干扰因素,这会影响到攻城狮对于电路数据的判断,ADI公司提供了不少高性能、低噪声的模拟器件,例如:

    低噪声、1 GHz FastFET 运算放大器 ADA4817-1:https://www.analog.com/cn/products/ada4817-1.html

    极低成本、高速FastFETTm运算放大器 AD8033:https://www.analog.com/cn/products/ad8033.html

    高电压、低噪声、低失真、单位增益稳定、高速、双通道…

  • RE: 这11大应用领域,你在里面么?

    仪器仪表和测量。在做光电探测器。使用过AD8033,AD8066,ADA4817-1.现在还是在设计测试阶段。希望搞出套低噪声,高带宽的光电前置放大器。
