Good morning. I am trying to find a Programmable Gain Amplifier with these characteristics:
- Simetrical supply- Digitally programmable (ex. SPI)- LB > 11 MHz (o AD8326 até vai até 100 MHz)
- (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...
This is the only one i have found with simetrical supply...and digitally programmable. Why only one?
Is there another solution?
Perhaps the same approach, but using the AD8336. This has dual supplies. Would this work out for you?
