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?
