TLE2064: TLE2064 quad op-amp

Part Number: TLE2064

We plan to use TLE2064 in our design with single supply from +5V as well  as +12V. Can we use in this configurations?

    Hi Saurabh,

    have you seen the "recommended operation conditions" in the datasheet?

    A minimum supply voltage of +/-3.5V corresponds to a minimum single supply voltage of +7V. So, your single supply voltage of +5V is too low but the +12V, on the other hand, is acceptable.

    Keep in mind, though, that the TLE2064 is no rail-to-rail OPAmp. So, it has a very limited common mode input voltage range and the output voltage cannot swing to the rails. Have a look into the datasheet please. ("Rail" is here another word for supply voltage.)

    Hello Saurabh,

    I agree with Kai.  The part will not be able to handle the single, +5V supply.

    To further clarify Kai's second comment, a quick jog through the datasheet will show the low end of the input common mode voltage is about 3V above the negative rail.  So, this part may not be desirable for your +15V application either.  Although, it will depend on your needs for the input and output voltage ranges.

    I would be happy to help you select a new part.

    Regards,

    Daniel

    Hari,

    Yes.  That is well within the recommended operating conditions for the device supplies in the datasheet.
