LM2903-Q1 recommended operating range of VCC

Other Parts Discussed in Thread: LM2903-Q1

Hello,

Please answer about LM2903-Q1 recommended operating range of VCC.

For VCC range datasheet has following explanations.

 

<Page 1>

Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage.

 

  <Page 1>

  “ORDERING INFORMATION” table

   LM2903VQDRQ1 and LM2903AVQDRQ1: MAX Vcc 32V

 

Please advice recommended operating VCC range of LM2903-Q1.

(Customer is looking for comparator that work with higher VCC .

And in case of recommended VCC range is 32V, I can not recommend LM2903-Q1.)

 

Beast Regards.

    Ushikubo_san,

    I am Toshimi.
    I will inform of you about the range of Vcc.

    <Recommended>
    a) VCC= 2V to 30V for non-V devices(LM2903QDRQ1,LM2903QPWRQ1)
    b) VCC= 2V to 32V for V-suffix devices (LM2903VQDRQ1,LM2903VQPWRQ1,LM2903AVQDRQ1,LM2903AVQPWRQ1)

    < ABS >
    a) VCC < 36V
    b) Input voltage range, VI (either input) = −0.3 V to 36 V

    <Note>
    The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V.
    The upper end of the common-mode voltage range is VCC+ − 1.5 V for the inverting input (−), and the non-inverting
    input (+) can exceed the VCC level; the comparator provides a proper output state.

    Best regards,
