  RE: High Speed amplifier design with high gain

  You need a gain bandwidth product of at least 2.5 GHz, and the offset voltage should be much smaller than the signal. The search function points to the OPA847. Also see the technical articles and appnotes linked on that page. What is the purpose of...

  RE: OPA847: OPA847 oscillating in high frequency.

  Hi Michael, I still was not able to solve 20MHz (sometimes 17MHz) oscillation. I tried the following things: 1. Putting the 10uF Aluminium electrolytic capacitor. 2. Removing 0402/10pF - Ceramic cap and replacing them with 0603/0.1uF Ceramic cap...

  OPA847: Model not working due to undefined model in switch

  Part Number: OPA847 Hello I have the same problem as mentioned in the thread linked to this post. The model of the OPA847 that I imported into ADS doesn't work, apparently due to syntax errors in the model of the switches. I get the following...

  OPA847: Minimum Gain

  TI Thinks Resolved

  Part Number: OPA847 Hi, In the OPA847's datasheet is mentioned that the amplifier is stable down to gains as low as +12 V/V. Is it possible to operate with a voltage gain of 6.3 V/V (to obtain Gp = 10dBm with 50 ohm source and load)? In what conditions...

  OPA847: Driving capacitive loads

  TI Thinks Resolved

  Part Number: OPA847 The OPA847 datasheet gives recommendations for driving capacitive loads by adding an isolation resistor on the output pin of the opamp: The criterion for setting the RS resistor is a maximum bandwidth, flat frequency response at...
