TLC372: TLC372IP alternative

Daria Kiseleva
Intellectual 1795 points
Part Number: TLC372
Other Parts Discussed in Thread: LM2903-N, LM2903, TLV1702, TLV1822, LM393

Hi Team,

Do we have an alternative device in DIP package besides the LM2903P?

1) Pin compatibility and the same design, i.e. THT, because we do not want to or cannot redesign existing PCBs
2) Temperature range, i.e. -40°C ... +85°C
3) Voltage supply range, i.e. 2...18 V must be covered
4) Current consumption without load, i.e. 300 µA at Vdd=5V and TA=25°C
5) Input voltage range, i.e. 0...Vdd-1.5

Thank you,

Daria

    Only the LM2903 and LM2903-N match these requirements.

    As bipolar devices, the LM2903(-N) consume about 0.8 mA (total for both comparators). If you want to use a power-saving CMOS device like the TLV1822 or TLV1702, you need to use an SMD-to-DIP adapter.

    Hi Clemens,

    Do you have the recommended SMD-to-DIP adapters manufacturers?

    Thank you,

    Daria

    Hi Daria,

    Don't expect to find new devices in DIP. We are not releasing new devices in DIP. The DIP's that are available now are just to support legacy customers on older devices - and their days may be limited. Any DIP's available are from the LM393 family (as Clemens mentioned).

    There are many adapters. Aries is the big one, but places such as Chip-Quick, Sparkfun and many Chinese manufacturers.

    They are available from distributors such as Digikey and Mouser (in the prototyping section), or eBay and Amazon.

    Just do an internet search for "SOIC to DIP adapter" or "VSSOP to DIP" adapter, and you should get plenty of results.

    You could buy adapter boards and then add the opamp chip (soldering them yourself, or done by a third party), but it might also make sense to create your own adapter board design so that the entire adapter can be manufactured by your existing board manufacturer in one step.

    Thanks Clemens for your suggestions. I hope these help you Daria.
