LM318 SPICE model
#1

Любителям старины посвящается


The following parameters are modeled:
1. Open loop gain and phase with RL and CL effects
2. AC/DC Common mode rejection ratio
3. AC/DC Power supply rejection ratio
4. Slew rate
5. Input voltage noise with 1/f
6. Input curent noise with 1/f
7. Input bias current with common mode and temperature effects
8. Input offset current with temperature effects
9. Input offset voltage with temperature effects
10. Input impedance
11. Output current through the supply rails
12. Output current limit with temperature effects
13. Output voltage swing from rails with RL effects
14. Output impedance
15. Quiescent current vs Supply voltage with temperature effects
16. Maximum supply voltage breakdown
17. Overload recovery / No phase reversal
18. Input common mode voltage range

Сделал три модели 318 согласно измеренным данным:
LM318NS_SN - National Semiconductor
LM318TI_SN - Texas Instruments
LT318A_SN - Linear Technology

Модели в первом посте.

Апдейтнул все DC параметры (мернул >10шт) и мернул и апдейтнул AC PSRR
