TLV6703: Using TLV6710 TINA model for TLV6703 simulation?

Part Number: TLV6703
Other Parts Discussed in Thread: TLV6710,

Team,

-Is it possible to use the TLV6710 TINA model for simulating the TLV6703?
-The overall electrical specs are very close so I guess that it could be realistic to do so.  What do you think?
-Is there something specific to pay attention too so that the simulation would apply to TLV6703 as well?

From the high level comparaison I see the that propagation delay and VICR (Max ) are different.

Thanks in advance,

    Hi AnBer,

     

    TLV6703

    TLV6710

    High to low Prop Delay

    18us

    9.9us

    Output Fall time

    0.22us

    0.12us

    Positive going input threshold

    400mV

    A: 405.5mV

    B: 400mV

    Negative going input threshold

    394.5mV

    A: 400mV

    B: 394.5mV

    VDD_max

    20V

    40V

    VOUT_max

    20V

    28V

    VIN_max

    6.5V

    1.7V

    As long as the simulation uses supplies that are compatible with the TLV6703 and an input voltage at or less than 1.7V, you can get accurate simulation results by simulating with the TLV6710. I modified the TINA file for the non-inverting input on the TLV6710 to have the same positive and negative going thresholds as the TLV6703 (positive going of 400mV and negative going of 394.5mV). As long as you ground the INB- input and disconnect the OUTB output from the output node, it should work. If you want to input anything higher than 1.7V into the comparator I would just use a resistor divider. I attached a table with some of the key differences between the parts and a TINA file with the modified TLV6710 with the same hysteresis thresholds as the TLV6703.
