Wayne Chen (ex FAE)

Part Number: VCA2616

Hi Sirs,

My customer is looking for a VGA to support (1) 0.1Hz~200kHz operating range (2) High linearity on gain control. AD8336/37 are benchmarks and the VCA2616, LMH6505 and TL026 are candidates. Would you pls provide recommendations in this case?

Thank you and Best regards,

Wayne Chen

Hello Wayne,

I checked with our systems team regarding VCA2616.
VCA2616 doesn't support low-frequency operation. 1/f noise is higher at low frequency.
