Can I use AD8048 to  amplify  the signal from 500mV  to  4V       ??                                                                                                                                                                                                                              

I'm looking for the spice Macro-model for AD8048 250MHz, General Purpose Voltage Feedback Op Amp.  The link provided on the spice models site is actually for AD8047, which is only stable for G=+1.

有没有关于AD8048的参考电路或者有关AD8048评估板的资料

Hello, 

I'm wondering how many transistor and/or effective gates are in the AD8048 and AD8031. 

Thank you for any information might be available and happy new year

Hello,

I have to measure the current of a photodiode.

Input signal is:

• Maximum current 15uA.
• Frequency of the pulsed current 4MHz
• Photodiode capacitance: 1pF

I have done the desing using the AD8067.

I have obteined good results, but i…
