TLV271-Q1: Slew rate spec

Shuji Ishiwata

Part Number: TLV271-Q1
Other Parts Discussed in Thread: TINA-TI, TLV271

Hi All,

I have a question about the specs on the TLV271Q datasheet.

Have you checked the above contents with the same circuit diagram as the one below? Any special schematics?

Best Regards,
Ishiwata

    Hi Ishiwata,

    I would take figures 18 and 19 of datasheet as a reference for the slew rate circuit.

    Take care: While the slew rate of TLV271 is specified as 2.4V/us in the datasheet, the TINA-TI simulation is only showing about 0.28V/us. And the Spice model does not properly simulate load capacitance effects either. This has to do with the fact that the model of TLV271 is highly simplified and outdated.

    Ishiwata-san,

    The figures that Kai mentioned are measured data. 

    Your image is correct. The input amplitude is 1/2 of the supply voltage. VIL = 1/4 and VIH = 3/4
