Other Parts Discussed in Thread: DEM-OPA-SO-1A , LMH6702 上一小节从理论上分析了CFB运放负向输入端的分布电容的影响。大家可能觉得还是很空洞。下面将从实验结果来验证上面的理论。（我总是喜欢先从理论的角度分析一个问题，然后再用实验来验证。有了实验结果，会让理论更形象，也更让人记忆深刻）。
下面是工程师Michael Steffes用老的CFB运放做的实验结果。它在上一小节的输入电容的位置，分别用0.5pF和5pF的电容做的实验。当负相输入电容为5pF时…
Other Parts Discussed in Thread: OPA690 , DEM-OPA-SO-1A 工程师您好：我用OPA690实现了一个负电阻电路，在没有任何输入的情况下，给负电阻电路提供正负5V的供电电压，发现输出端的电压一会是3.773V，一会又变为-3.821V，这是什么原因呢？ 在电路中反馈电阻R=46Ω，
Part Number: OPA657 Other Parts Discussed in Thread: DEM-OPA-SOT-1A ,
Dear all,
here is my schematic
my PCB design is close to DEM-OPA-SOT-1A
Input is a photomultiplier tube . its parasite capacitance i estimate is 20-30pF ,and so i choose C5=0.25pF.
…

Part Number: TPS54335-1A Hello
We have developing industrial products with TPS54335-1ADRCR for a long time， and found in the data that Tj of IC is 150 degree。The recent design is 12V to 3.3V with current 1A MAX,and operating air temperature is 100…
Part Number: OPA2277 Dear TI Support Team, We have received two separate lots of the OPA2277U (SOIC-8, orderable device OPA2277U/2K5) and performed X-ray inspection on both. The images reveal a noticeable difference in the appearance of the silicon die inside the packages. Could you please co…
