TLV4021: TLV4021

Part Number: TLV4021

Hi Team,

In one of our projects we are going to use an Analog comparator with Part number TLV4021R2/TLV4041R2.

Requirement as per our design,

1) Input should be Non-Inverting input.

2) Vref is below 1.2V as my input voltage is having an amplitude of 1.2V

3) The package should be SOT23-5

As per the datasheet, I have not found any sample part (MPN) for the above application.

So, please suggest me the part with Vref is less than 1.2V (Ex: 0.5V or 0.2V)

Thanks,

Manikanta

    Hi Clemens,

    The part which was suggested by you is TLV4041‍R5DBVR having a reference voltage of 1.2V.

    But my voltage level at the non inverting input is 1.2V only.

    If we are going to use this part, I may not get the high logic output.

    So please suggest the appropriate MPN for the same.

    Thanks,

    Manikanta

    Hi Manikanta,

    I would recommend TLV4041R2 based on your requirements. The TLV4041R2 has an internal reference of 0.2V.

    Regards,

    Joe

    According to table 1, the TL4V4041R5 has a reference voltage of 0.5 V. (It would not make sense that R1 and R5 are identical.)

  • In reply to Clemens Ladisch:

    Hi Clemens,

    Thank you for your support and you are right about the internal reference value of 0.5V for the TLV4051R5.

    Both my suggestion and Clemens should work for you, Manikanta.

    Regards,

    Joe

    Hi Clemen,

    In the Table 1, it was very clear about the device.

    But if you look at the MPNs, no one is matching w.r.t 0.2V or 0.5V reference voltage of Non-inverting type of input.

    Please have a look at it.

    Thanks,

    Manikanta

    Hi Clemen,

    The package information is attached for reference.

    We are looking for a non-inverting and SOT23 package only.

    Thanks,

    Manikanta

    Sorry for joining the support late but what is your question?  If you require a SOT23 package with non-inverting configuration, the TLV4041R5 is your only option from this product family.  And as noted previously, the reference voltage is 0.5V.

    Chuck,

    Thanks for the confirmation.
