PGA870: Selection of Programmable Gain Amplifier

Vishaal S

Part Number: PGA870

Hi sir/Madam,

This is Vishaal working as an Hardware Engineer. We are currently in search of a PGA - (Input Voltage range 1.5V to 4V) which is suitable for our application. Please suggest a suitable PGA with bandwidth higher than 15MHz either SPI/I2C Interface, single ended input and able to process 0.6 vpp amplitude signals as soon as possible.

Thanks,

Vishaal S

Will analog input VGA work ? You will have to use an external DAC to convert to analog from the incoming digital interface ?

What is the distortion needed at 15MHz ?

Hi Shreenidhi Patil,

As we have a size constraint for the application so we wont be able to use an external DAC. And as our max bandwidth is 12.5MHz from our wave form generator with which PGA will be interfaced to amplify the waveform so, we will be using under the max bandwidth only. It would be helpful if you suggest the suitable PGA itself.

Thanks,

Vishaal S
