LM360: LM360MX/NOPB

Dong Ba
Intellectual 895 points
Part Number: LM360
Other Parts Discussed in Thread: TL3116

Hi Team,

The customer has a question about whether LM360MX/NOPB can be used with Vcc+=10V and Vcc-=GND? 

If yes, How about the input and output Range?

Common Mode Input Voltage Range

Differential Input Voltage Range

Output High Voltage (Either Output)

Output Low Voltage (Either Output)

B.R.

    Hello Ba,

    I believe it can be used on a single 10V supply, though the datasheet does not specify the maximum allowable voltage difference between Vcc+ and the GND pin, so this makes me a little nervous.

    The datasheet was written assuming split supplies, so a little "translation" is required.

    The LM360 is not a Rail to Rail input, and has a limited input voltage range. The inputs cannot go more then than 2.5 V close to either rail.

    So with a +10V supply, the input range is limited to +2.5V to +7.5V.

    Assuming the GND pin is connected with Vcc-, then the output will swing +0.4V to +8.5V.

    Is there a reason they are looking at such an old device??

    I would suggest looking at a "newer" device such as the TL3116, which is designed for single supplies and has inputs that can go down to ground (0V to +7.5V input range) and a little better output swing.

    Hello Ba,

    Actually, I think the TL3116 will have the same problem with the Vcc+ to GND voltage difference limit.

    Can they operate at +5V? Do they need the full output swing?

    Can you share the application or requirements?

    There has been no update on this post for a while, so I will assume that the question was resolved or further support is no longer needed.

    If you have additional information to share, feel free to respond or open a new post.  Another option is to take this offline.
