THS3120: Looking for recommendation for high-speed, high-current output capability amplifier

Daniel Ruiz

Part Number: THS3120
Other Parts Discussed in Thread: , THS6012, OPA2673

Hi,

Is there a newer, higher-current amp you would recommend over THS3120? I am planning on designing a setup to test PSRR as described in the SLAA414 application note. The application note shows an example using the THS3120EVM as a summing amplifier. Since the app note is from back in 2009, I figured I would just ask the experts if you recommend a different part.

My main care-about is higher current output capability.

Thanks,

- Daniel

Hi Daniel,

Would you be okay in reducing the device operating supply voltage? We do have the OPA2673 that provides 700mA of output current but operates on +/-6V supply. A slightly higher output current capability than the THS3120 is the THS6012.

Best Regards,
Rohit

Thanks for the prompt assistance, Rohit! I will look into both of these alternatives.
