10.1.1 TINA-TI™ Simulation Model Features

The TINA-TI™ simulation software device model is available on the product folder www.ti.com in a typical application circuit file. The model includes numerous features intended to speed designer progress over a wide range of application requirements. The following list shows the performance parameters included in the model:

  • For the small-signal response shape with any external circuit:
    • Differential open-loop gain and phase
    • Parasitic input capacitance
    • Open-loop differential output impedance
  • For noise simulations:
    • Input differential spot voltage noise and a 100-Hz 1/f corner
    • Input current noise on each input with a 6-kHz 1/f corner
  • For time-domain, step-response simulations:
    • Differential slew rate
    • I/O headroom models to predict clipping
    • Input stage diodes to predict overdrive limiting
  • Fine-scale, dc precision terms:
    • PSRR
    • CMRR
    • Nominal input offset voltage
    • Nominal input offset current
    • Nominal input bias current

The Typical Characteristics table provides more detail than the macromodels can provide. Some of the unmodeled features include:

  • Harmonic distortion
  • Temperature drift in dc error (VIO and IOS)
  • Overdrive recovery time
  • Turn-on and turn-off times using the power-down feature
