I'm want realize gain G=+1 with OPA AD8009. For this gain recomended resister Rf = 301 Ohm in Data Sheet. How many value Rg with Rf = 301 Ohm for G=+1 for AD8009?
1. AD8009 is on the output of the device. AD8313 provides an output voltage (dc if the input level is fixed) that is proportional to the size of the input signal. So AD8009 is not seeing a 2.5 GHz signal.
2. According to the schematic, the switch should…
ADA4927 has achieved better results than ad8009 at simulations (I haven't had physically connected it yet). The fastest pulse at input should be from comparator ad8561 - 5V / 1.5 ns. It appears that input impedances are more equal for…
The problem may stem form the input source impedance driving the AD8009. The AD8009 does not like source input impedances much higher than 200 ohms. How are you drving the AD8009? As for other high speed current feedback amplifiers, I'd…
The AD8009 is maufactured using an analog complementary bipolar process.
Thanks very much for your reply.
We modified the circuit configration as the following one, and now it works fine.
It is an actual circuit on printed circuit board. The photodiode is an APD, the Vbias is 28V. The photodiode is work on geiger…
Can these amplifiers be powered from a single +12V power supply. The datasheet only shows +/-5 V and 5V; however the max. power supply is set to +12.6 V in the datasheet.
Or, when operation between +/- 5V is only feasible, can I use a RF transformer…
