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
