TLV7011: suggestion of dual channel, high precision, rail-rail amp

Part Number: TLV7011
Other Parts Discussed in Thread: TLV9002, TLV9062, OPA2391, OPA2392, OPA2347, OPA2376, TLV9042, TLV9052, OPA2316

Tool/software:

Hi,

I am looking for a dual channel high precision rail to rail op amp, with the smallest package possible. One channel will be a differential op amp, with a differential range of 1.6V, and a gain of 3. Whilst the other channel will be a non-inverting amplifier with a gain of 76.

Please let me know if you can recommend a suitable device. Ideally it should be powered by a 5V source.

For now, I have considered using 2 separate TLV7011, with the X2SON package. Please let me know if you have any recommendations which fit better to the requirements above?

BR, Ross

    The TLV7011 is a comparator.

    1.00 mm²: YCK (DSBGA): TLV9002, TLV9062
    1.44 mm²: YBJ (DSBGA): OPA2391, OPA2392
    2.97 mm²: YZD (DSBGA): OPA2376, OPA2347
    3.00 mm²: RUG (X2QFN): TLV9002, TLV9042, TLV9052, TLV9062, OAP2310, OPA2316

    Hi Ross,

    As Clemens said, TLV7011 is a comparator, not an op amp.

    Clemens made nice suggestions with small-size DSBGA packages, but is there any other information you can provide than gain?

    For example:

    What is the frequency and amplitude of the input signals?

    What application are these op amps going to be used in?

    Is this a precision application that needs low offset/drift?

    Feel free to reach out via email as well.
