Good night people.
I am trying to find a Programmable Gain Amplifier with these characteristics:
- Simetrical supply
- Digitally programmable (ex. SPI)
- LB > 10 MHz
- A wide range of gains
- (If possible) with a Power Amplifier inside with 50 ohms output impedance
The closest i've found with these requirements is AD8326 but the PA has a 75 ohms output impedance...
There is another one that accomplishes almost all those requirements: AD8250, but then there are only 4 possible gains (1, 2, 5 and 10) :S
I have searched at Farnell, Maxim, AD ...
Do you know any other topology i can use to amplify a signal between -0.3 V and 0.3 V with those requirements? Or maybe another amplifier i am not considering?
Could you help me?
