LMH6881: LMH6881 for 3.3V-VCC applications

Part Number: LMH6881
Other Parts Discussed in Thread: LMH6401

Dear TI Applications Rep,

1) Does LMH6881 can operate at supply voltage of 3.3V?

2) Is there a 3.3v version of this device available under different PN?

3) Is there any test performed with  3.3V supply and a list desegregate parameters that maybe tolerable?

  • Hello Cyrus,

    The LMH6881 is a high speed device, so I am moving your question to the High Speed Amplifiers forum.

  • Hi Cyrus,

    1. The LMH6881 cannot operate at supply voltages of 3.3V.

    2. I don't think there is a 3.3V version of the device available under different PN. The lowest power supply programmable gain amplifier we have is the LMH6401 which runs on 4.0V power supply. The LMH6401 could be used as an upgrade to the LMH6881.

    3. I don't think there is any test performed with 3.3V supply on the LMH6881. The bare minimum or lowest the LMH6881 can go on power supply is 4.5V, which is actually beyond its recommended operating supply range.

    Best Regards,
