TLE2022: Datasheet

Ray Vincent Aranzaso
Genius 13495 points
Part Number: TLE2022

Hi,

Good Day.

I quite do not understand the datasheet, especially absolute maximum ratings, especially note 1.

Maybe a more detailed case: what is the maximum voltage which may be applied to Vcc (V+) when Vcc- (V-) is connected to ground (0V)?

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Hi Ray,

    the TLE2022 is from 1989 and at that time OPAmps were usually powered by bipolar (or "split" or "symmetrical") supply voltages, typically +/-15V. See figures 1b, 2b, 3b and 4b of datasheet. So, the supply voltages consisted of three potentials, the positive supply voltage, the negative supply voltage and signal ground (= power ground). Signal ground would be the midpoint between the positive supply voltage and the negative supply voltage. This is what "note 1" of the "absolute maximum ratings" wants to say.

    This would be +40V.

    As Kai explained, the TLE2022 Absolute Maximum Rated supply voltage is +/-20V (in dual supply) or 40V (in single supply) BUT you need to be aware that the part should NOT be operated at 40V for any extended period of time as this may affect device reliability - see below.

    Also, please be aware that input and output voltage range is a function of supply voltage used - see below.  Thus, for the maximum specified 30V single supply the input common-mode voltage is from 0V to 28.5V while the output range is from 1.3V to 28.9V - see below.
