LMH6639: LMH6639 PSPICE Model

TADAMASA MURAKAMI
Prodigy 80 points

Part Number: LMH6639

Tool/software:

Hello there

I'd like to know temperature characteristic of LMH6639 PSPICE Model.

Is the simulation result reliable for temperature dependence of oscillation frequency

when I use this model for an oscillator simulation for temp range  20~80deg?

Thanks,

Murakami

    Hello Murakami,

      The model is built with components that are temperature dependent. However, this is generic temperature curve depending on component used in simulation (i.e. resistor, diode, capacitor, transistor type), and not device specific such as drift parameters or other characterized data over temperature in datasheet. 

       Looking at tested data, AC response tracks for -40C to 85C, therefore, there will not be a significant impact of oscillation frequency due to the amplifier. 

    Thank you,

    Sima
